picture"/></figure><div class="styles_content__2kzfW"><h5>Increase your contents’ discoverability and prevent its misuse</h5><p>Inclusion in CORE ensures the widest possible dissemination of your open access content, resulting in increased visibility and discoverability of your papers. We achieve this by promoting your content to over 30 million monthly active users of CORE. Your content will be discoverable not just in CORE Search, but also across the open access network, within the systems of hundreds of data providers using the CORE Recommender (such as arxiv.org) and CORE Discovery plugins. We also integrate with PMC LinkOut and there are dozens of mission-driven third-party services that have been built on top of our aggregated data, such as the Pocket Open Access mobile app and the Lean Library discovery service. By cooperating with world-leading plagiarism detection solutions, we also facilitate early-detection and prevention of misuse of content produced by your staff.</p><p>A study of 21 UK institutions carried out in 2019 showed that when a repository is indexed by CORE, the number of content downloads increases by 15% on average and up to 32% if the repository is well configured for indexing.</p><div class="styles_info-wrapper__2ACFa"><span class="styles_info__1BBEl">With millions of monthly active users, it matters to become a data provider and show to the world that your content is indexed.</span><button class="button-button-3fr3r button-text-2Jjil"><img src="/images/benefits/indexed-by-core.svg" alt="With millions of monthly active users, it matters to become a data provider and show to the world that your content is indexed."/></button></div></div></div><div class="styles_services__1udt4"><figure><img class="styles_image__Zh2s4" src="/images/logo/OAI-resolver.png" alt="Make your papers uniquelly identifiable and resolvable with PIDs's picture"/></figure><div class="styles_content__2kzfW"><h5>Make your papers uniquelly identifiable and resolvable with PIDs</h5><p>Identifiers of metadata records indexed by CORE are automatically registered as globally unique persistent identifiers (PIDs). CORE uses for this purpose <a target="_blank" href="/documentation/oai-resolver">OAI identifiers</a> that have been almost universaly adopted across the network of open access repositories and publishers. OAI identifiers are viable PIDs for repositories, publishers and archives that can be, as opposed to DOIs, minted in a distributed fashion and cost-free, and that are resolvable directly to the data provider rather than, as is typical with DOIs, to the publisher’s website. As a result, OAIs are highly suitable identifiers supporting the green (self-archiving) route to Open Access, envisaged by the Budapest Open Access Initiative. Data providers are encouraged to freely register their OAI prefix with CORE (using the CORE Dashboard) to benefit from our global <a target="_self" href="https://oai.core.ac.uk/">OAI Resolver</a>.</p></div></div><div class="styles_services__1udt4"><figure><img class="styles_image__Zh2s4" src="/images/illustrations/data-points-amico.svg" alt="Assess and contribute to Open Access compliance and FAIRness's picture"/></figure><div class="styles_content__2kzfW"><h5>Assess and contribute to Open Access compliance and FAIRness</h5><p>In the context of rapidly increasing open access policies (such as REF, UKRI or Plan S) and best practices (such as FAIR), CORE can improve the understanding of your content’s status and help you prepare analytical reports for research administrators and funders. For example, CORE conducted the UK REF2021 open access audit, verifying when outputs became publicly available as open access.</p><p>By being included in CORE, your infrastructure contributes to the national and international monitoring of open access content growth and enables the prediction of new trends in scientific disciplines. Join our vast network of interoperable repositories and journals and take advantage of metadata enrichments, e.g. recommendations, DOIs, ORCID iDs, etc.</p></div></div><div class="styles_services__1udt4"><figure><img class="styles_image__Zh2s4" src="/images/benefits/content-machine-readable.svg" alt="Make your content machine readable's picture"/></figure><div class="styles_content__2kzfW"><h5>Make your content machine readable</h5><p>Open access content hosted in repository and journal platforms is typically not easily usable in analytical, text and data mining tasks. However, creators of innovative research tools, funders and researchers themselves frequently need research content in a well-structured machine readable format, a prerequisite for a wide range of use cases, including domain specific research search engines, plagiarism detection, fact checking and misinformation detection, research graphs, rapid systematic reviews, detection of research trends, research assessment, identifying suitable peer-reviewers, recommender systems, innovation engineering, compliance monitoring, etc. CORE provides access to open access content in a machine readable format doing all the heavy lifting with the help of AI. This involves harmonising metadata, cleaning and creating a structured representation of scholarly data.</p></div></div><div class="styles_services__1udt4"><figure><img class="styles_image__Zh2s4" src="/images/membership/international-cooperation.svg" alt="Become a CORE Member and benefit from lots more's picture"/></figure><div class="styles_content__2kzfW"><h5>Become a CORE Member and benefit from lots more</h5><p>After joining as a data provider, you will be able to become a <a target="_blank" href="/membership">CORE Member</a>, giving you many more benefits, such as:</p><ul><li>Public recognition of your support for key Open Science infrastructure through display of your organisation’s logo and banners within CORE Search and across the CORE ecosystem.</li><li>Participation in our governance programme.</li><li>Guaranteed technical support for your repository.</li><li>Access to the CORE Repository Dashboard loaded with tools for Open Access compliance checking, metadata quality validation, enrichment and assessment of repository health.</li><li>Access to raw data services for your organisation: CORE API and CORE Dataset.</li></ul></div></div></section><section class="styles_container__3Krg3 styles_statistic__15Uht" id="statistic" caption="statistic"><h4 class="styles_title__3i5x0">How many data providers have joined CORE?</h4><div class="styles_stats__1nXFY"><div><div class="styles_stat-title__jjNrs">Last quarter</div><p><mark>774</mark></p></div><div><div class="styles_stat-title__jjNrs">last year</div><p><mark>1K</mark></p></div><div><div class="styles_stat-title__jjNrs">all time</div><p><mark>12K</mark></p></div></div></section><section class="styles_container__3Krg3" id="how-to-join"><h4 class="styles_title__3i5x0">How to join?</h4><div class="styles_item-wrapper__1ciwE"><div class="styles_item__s1QQ5"><div><img class="styles_title-picture__bv3UN" src="/images/benefits/join-circle.svg" alt="Step 1"/><span class="styles_join-title__3FNfY">Step 1</span></div><div><div class="styles_item-description__1pqM-"><p>Submit the data provider OAI base URL into the form below.</p></div><img src="/images/benefits/join-arrow.svg" alt="Step 1"/></div></div><div class="styles_item__s1QQ5"><div><img class="styles_title-picture__bv3UN" src="/images/benefits/join-circle.svg" alt="Step 2"/><span class="styles_join-title__3FNfY">Step 2</span></div><div><div class="styles_item-description__1pqM-"><p>We will index your content and send an email once completed.</p></div><img src="/images/benefits/join-arrow.svg" alt="Step 2"/></div></div><div class="styles_item__s1QQ5"><div><img class="styles_title-picture__bv3UN" src="/images/benefits/join-circle.svg" alt="Step 3"/><span class="styles_join-title__3FNfY">Step 3</span></div><div><div class="styles_item-description__1pqM-"><p>Claim access to the <a target="_blank" href="/services/repository-dashboard">CORE Dashboard</a> to manage your content.</p></div><img src="/images/benefits/join-arrow.svg" alt="Step 3"/></div></div><div class="styles_item__s1QQ5"><div><img class="styles_title-picture__bv3UN" src="/images/benefits/join-circle.svg" alt="Step 4"/><span class="styles_join-title__3FNfY">Step 4</span></div><div><div class="styles_item-description__1pqM-"><p>Become a Supporting or Sustaining <a target="_blank" href="/membership">member</a> to receive even more benefits.</p></div><img src="/images/benefits/join-arrow.svg" alt="Step 4"/></div></div></div><div class="styles_docs-btn__2y_g5"><a class="button-button-3fr3r button-contained-pmIp-" href="/documentation/data-providers-guide">Data provider’s guide</a></div></section><section class="styles_container__3Krg3 styles_join-core__5rqpz" id="join-core" caption="join-core"><div class="styles_form-block__3Qba9"><div id="add-new-data-provider"><h5>Join CORE as a data provider and contribute to the creation of a mutually beneficial ecosystem.</h5><div class="styles_benefits-description__2D2_P"><p>We have created a <a target="_blank" href="documentation/data-providers-guide">data provider’s</a> guide describing best practices of how to expose metadata to CORE.

asked questions about CORE\n","sections":[{"id":"joining-core","title":"Joining CORE as data provider","updateDate":"Last updated 22.02.2024","caption":"Joining CORE","items":[{"slug":"is-my-repository-or-journal-indexed-by-CORE","question":"Is my repository or journal indexed by CORE?","answer":"To check whether your repository or journal is indexed\nby CORE, go to our data providers [list](/data-providers).\n"},{"slug":"how-do-I-register-my-repository-or-journal-with-CORE?","question":"How do I register my repository or journal with CORE?\n","answer":"CORE uses information from various registries, such as\n[OpenDOAR](http://opendoar.org/) and [DOAJ](https://doaj.org/),\nto include new repositories and journals into CORE.\nIf your repository or journal is already registered with\nsome authoritative registry, you don't need to do anything.\nIf your repository or journal has not been registered\nyet use [the form](~register-data-provider) to add it.\n"},{"slug":"where-are-the-repositories-indexed-by-CORE-located","question":"Where are the repositories indexed by CORE located?","answer":"CORE is an international service and indexes repositories from\nvarious locations around the world. This information is displayed in\na map at our [data providers page](/data-providers).\n"},{"slug":"I-would-like-to-include-them-in-CORE","question":"I am an author of scientific papers and I would like to include\nthem in CORE.\n","answer":"CORE is a indexing service and is not similar to research\nnetworking sites, e.g. ResearchGate or Academia.edu, where authors\ncan deposit papers, so please do not email us the full text of your\npapers. If you have deposited your articles in a repository\n[let us know](~contact) the name of the repository.\nThere are chances that we index it already and if we don’t we could\nstart indexing it.\n"},{"slug":"core-indexes-from-doaj","question":"CORE indexes from DOAJ but I cannot find my journal which is already\nregistered in DOAJ.\n","answer":"CORE indexes DOAJ as a single entry, which means that each journal\ntitle does not appear separately in CORE. If you wish to have a\nseparate entry for your journal in CORE, do [send us](~contact) the\njournal's OAI base URL and we will create a new entry.\n"}]},{"id":"Indexing","title":"Indexing","updateDate":"Last updated 22.02.2024","caption":"Indexing","sections":[{"id":"general-indexing","title":"General","items":[{"slug":"how-often-does-CORE-index-the-repositories","question":"How often does CORE index the repositories?\n","answer":"CORE does not index all the repositories that exist in our\ndatabase with the same frequency. Repositories are indexed\nas frequently as our HW infrastructure allows.\nThe specific time of indexing for a repository is determined\nby the CORE Scheduler. The CORE Scheduler is a software component\nthat ensures that our indexing cluster of machines is close to\nfully utilised 24/7 for 365 days every year. As soon as some\nresource is freed, the CORE Scheduler decides which repository\nneeds to be indexed based on several criteria. These criteria\ninclude, but are not limited to, the previous time of the repository\nbeing indexed, the size of the repository,\nthe location of the repository, the repository's indexing\nperformance and information about potential previous indexing\nerrors. We review the functionality of the scheduler on a regular\nbasis to ensure that its decisions on what to index next maximise\nthe number of ingested documents over a unit of time.\n\nIf you have a question regarding a specific\nrepository do [get in touch](~contact) with us.\n"},{"slug":"when-will-the-indexing-process-of-my-repository-be-completed","question":"When will the indexing process of my repository be completed?\n","answer":"Depending on the size of the repository and the existing traffic\nin CORE's servers, the indexing can last from a couple of hours\nto a couple of weeks. If we experience any technical issues\nduring that period, we will get in touch.\n"},{"slug":"what-types-of-scientific-outputs-does-CORE-provide","question":"What types of scientific outputs does CORE provide?\n","answer":"CORE indexes all metadata records in a repository, but it is in\nposition to index full text records in PDF only. We are working\nthough to include other file types, such as HTML webpages, images etc.\n"},{"slug":"can-my-repository-be-indexed-by-CORE","question":"My repository has plenty of metadata records, but not all of them\nhave an open access full text. Can my repository be indexed by CORE?\n","answer":"Yes it can, provided that the repository offers its content as\n[Open Access](~mission).\n"},{"slug":"my-repository-contains-a-much-higher-number-of-records-than-CORE","question":"My repository contains a much higher number of records than CORE.\nWhat can I do?\n","answer":"Log in to the [CORE Repository Dashboard](~services/repository-dashboard)\nand look under the issues tab. Examine whether CORE has the correct oai base\nurl of your repository or if there are any technical issues listed there.\nIf there are no technical issues or you do not have an account for the CORE\nRepository Dashboard [contact us](~contact).\n"},{"slug":"can-I-upload-a-new-version","question":"There is a mistake in my article, can I upload a new version?\n","answer":"CORE works at the level of repositories and cannot update specific\nrecords. You can upload the new record into your institutional\nrepository or journal and CORE will synchronise it at the next\nscheduled re-indexing.\n"},{"slug":"there-are-many-new-records-in-my-repository","question":"There are many new records in my repository. Do I need to notify CORE?\n","answer":"No, CORE follows an automated re-indexing process and your repository\nwill be re-indexed at the next automated re-indexing.\n"},{"slug":"core-vs-google-scholar","question":"How is CORE different from Google Scholar?\n","answer":"Google Scholar is a search engine containing scholarly research papers but it is not designed \nto collect information from repository and journal systems. More specifically:\n- Google Scholar crawls and indexes the full text of research papers that can be found on the web, \nwhile CORE indexes also the metadata as supplied by the repository opr journal system.\n- The audience is different. Even though CORE has a search engine in the same way as Google Scholar, \nCORE’s delivers value by making research information machine readable, delivering an open access scholarly \ninfrastructures which others can build on via the\n [CORE API](~services/api) and [Dataset](~services/dataset).\n"},{"slug":"metadata-in-the-CORE-display-page-are-wrong","question":"The metadata in the CORE display page are wrong. How can I have them corrected?\n","answer":"CORE does not create the metadata, but rather indexes\nthem from its content providers. If the metadata are wrong\nthen contact the repository or journal where you had originally\ndeposited or published your content.\n"},{"slug":"can-CORE-offer-any-statistics-about-the-content-it-indexes","question":"Can CORE offer any statistics about the content it indexes?\n","answer":"CORE can offer repository or journal full text download statistics per month via the\n[CORE Repository Dashboard](~services/repository-dashboard). If you do not have access to the Dashboard, \nyou can [claim it](~services/repository-dashboard).\n"},{"slug":"are-the-research-papers-offered-by-CORE-peer-reviewed","question":"Are the research papers offered by CORE peer-reviewed?\n","answer":"Yes it does. CORE indexes content from repositories and journals. The first\ndo not perform peer review of the deposited content but the latter\ndo. In some occassions the content deposited in a repository is already\npublished in a journal and is peer-reviewed. In addition, repositories may contain\ngrey literature and these resources are not peer-reviewed.\n"},{"slug":"how-is-the-record-count-in-OpenDOAR-estimated-by-CORE","question":"How is the record count in OpenDOAR estimated by CORE?\n","answer":"CORE has created definitions with regards to the statistics it provided to OpenDOAR.\n\n**Metadata:** The total number of metadata records with a unique OAI identifier provided\nby the repository as this appears in the application profile which CORE index -\nif CORE indexes from the RIOXX endpoint, CORE will provide RIOXX counts instead of Dublin Core counts.\n\n**Full text:** Count of metadata records - as above - with a least one attachment\nprovided by the repository being a pdf file, which a) is publicly downloadable\n(no-login required or output is not under embargo, etc.) and b) the full text is machine readable,\ni.e. it has an extractable text not via OCR.\n"},{"slug":"who-owns-the-rights-of-content-in-the-CORE-collection","question":"Who owns the rights of the content in the CORE collection?\n","answer":"CORE does not own any rights of the aggregated content and each\nresource has its own license, which should be respected\nby the CORE users.\n"},{"slug":"i-landed-at-a-core-url-linking-to-a-full-text-pdf-but-the-link-gives-a-404-error","question":"I landed at a CORE URL linking to a full text PDF but the link\ngives a 404 error. How can I access this output?\n","answer":"You cannot access it – a 404 error indicates that the full text\nhas been removed from CORE.\n"},{"slug":"my-repository-contains-a-mix-of-oa-and-non-oa-papers","question":"My repository contains a mix of OA and non-OA papers.\nCan I ask CORE to limit indexing only to OA papers?\n","answer":"Yes, this is possible.\nPlease contact us and we will enable this for your repository.\n"}]},{"id":"technical-aggregation","title":"Technical","items":[{"slug":"what-are-the-technical-requirements-for-being-aggregated","question":"What are the technical requirements for being aggregated?\n","answer":"In order to realise the data transfer and regular data updates of\nCORE and your system, CORE uses a variety of protocols to ingest\nthe content. The easiest way to get your content integrated with CORE\nis the [OAI-PMH protocol](https://www.openarchives.org/pmh/).\nIf you wish to join CORE get in [touch](~contact).\n"},{"slug":"what-is-oai-base-url","question":"What is my journal’s/repository’s OAI base URL?\n","answer":"OAI base URL looks similar to `http://journaldomain.com/cgi/oai2` or\n`http://journaldomain.com/oai/request` when homepage URL is\n`http://journaldomain.com`. CORE cannot index the\njournal’s/repository’s content via its webpage URL.\nIf you are not sure whether your journal/repository has an OAI base\nURL, [contact our team](~contact) and we will provide\ntechnical support to you.\n"},{"slug":"oai-about","question":"What is an OAI Identifier?\n","answer":"A more technical answer for \u003ca href='https://support.core.ac.uk'\u003ehttps://support.core.ac.uk\u003c/a\u003e \u003cbr/\u003e\nTarget audience: repository managers, Technical staff. \u003cbr/\u003e\u003cbr/\u003e\nAn OAI Identifier is a unique identifier which distinguishes items in a repository.\nIt \u003ca href ='http://www.openarchives.org/OAI/openarchivesprotocol.html#UniqueIdentifier'\u003e“unambiguously identifies an\nitem within a repository; the unique identifier is used in OAI-PMH requests for extracting metadata\nfrom the item”\u003c/a\u003e \u003cbr/\u003e\u003cbr/\u003e\nThe Identifier contains 3 parts, split using: \u003cbr/\u003e\n“oai“ : Unique identifier oai.

In some repository\nsystems, such as EPrints, most of these recommendations are\nfollowed by default. Find more details [how it\nworks](~about#how-it-works).\n"},{"slug":"which-metadata-formats-does-CORE-support","question":"Which metadata formats does CORE support?\n","answer":"We mainly support oai\\_dc, the mainstream metadata format used in the\n[OAI-PMH Protocol](http://www.openarchives.org/OAI/openarchivesprotocol.html),\nutilising the [Dublin Core](http://dublincore.org/documents/dcmi-terms/)\nvocabulary, a popular vocabulary for bibliographic data.\nWe also support [RIOXX](http://rioxx.net/), a richer metadata\nprotocol, used mostly by the UK repositories.\n"},{"slug":"can-CORE-just-index-our-content-but-not-store-it-on-its-servers","question":"Can CORE just index our content, but not store it on its servers?\n","answer":"To provide its service, it is essential for CORE to be able to store\na cached copy of the indexed content. This is needed to verify open\naccess sources, offer analytical services, support text and data mining,\nrecommendation tools, etc. By cashing a copy of the indexed\nresource, CORE is not different from many commercial and\nnon-commercial, academic and non-academic, search engines including\nGoogle or CiteSeerX.\nThe primary difference from such systems is that CORE caches only\ncopies of open access content. More information on the benefits of\nthis approach is available in the “[CORE: Three Access Levels to\nUnderpin Open Access](http://www.dlib.org/dlib/november12/knoth/11knoth.html)”\narticle.\n"},{"slug":"how-can-my-repository-opt-out-from-being-indexed-by-CORE","question":"How can my repository opt out from being indexed by CORE?\n","answer":"CORE uses information from various registries, such as\n[OpenDOAR](http://opendoar.org/), to include new repositories,\njournals and archives into CORE. If the circumstances have changed in\nyour repository, you can restrict indexing and crawling activities\nby modifying your rules in your “robots.txt” file by using the\n[Standard for Robots Exclusion](http://www.robotstxt.org/orig.html).\nThis will also guarantee the content cannot be cached by search\nengines and indexing systems. In addition, you could withdraw your\nrepository from all open access registries lists; when this takes\nplace, please [notify us](~contact).\n"}]},{"id":"removing-full-text-or-metadata","title":"Removing full text or metadata","items":[{"slug":"how-does-CORE-ensure-that-the-indexed-content-is-Open-Access","question":"How does CORE ensure that the indexed content is Open Access?\n","answer":"CORE aggregates content from repositories registered in\n[OpenDOAR](http://www.opendoar.org), journals registered\nin [DOAJ](http://www.doaj.org) or those content providers that\nrequested their content to be aggregated. This means that all the\ncontent sources aggregated by CORE must be open access as this is a\nrequirement for the providers to be included in these registries.\nAccording to the official [BOAI definition of open\naccess](http://www.opensocietyfoundations.org/openaccess/boai-10-recommendations),\nCORE is allowed to, _\"distribute, search, or link to the full\ntexts of articles, crawl them for indexing, pass them as data\nto software, or use them for any other lawful purpose, without\nfinancial, legal, or technical barriers other than those\ninseparable from gaining access to the Internet itself. The only\nconstraint on reproduction and distribution, and the only role for\ncopyright in this domain is to give authors control over the\nintegrity of their work and the right to be properly acknowledged\nand cited.\"_\n"},{"slug":"CORE-indexes-copyrighted-material-from-my-repository","question":"CORE indexes copyrighted material from my repository\n","answer":"CORE’s system is fully automated and relies on data made available\nin a machine readable form. If your repository hosts full text with\na restrictive license that prohibits indexing, this needs to be\nproperly communicated in a machine readable form. All non open\naccess items should be blocked in the robots.txt file. If this\ninformation is provided in the metadata for each record and CORE\nexposes the full text, please get in [touch](~contact) with us.\n"},{"slug":"retrieve-license-information","question":"How can I retrieve the license information (CC-BY, CC-BY-NC, etc.)\nfrom the indexes outputs?\n","answer":"An output's license is not consistently exposed by content providers in a\nmachine readable form. In some circumstances it may be possible to extract\nthis from the \"fulltextUrls\" field in the [CORE API](~services/api). However, this is\nsubject to the license the data offered by the data provider.\n"},{"slug":"full-text-record-is-deleted-from-my-repository","question":"A full text record is deleted from my repository, but is still\navailable in CORE\n","answer":"CORE’s system is fully automated and relies on data made available\nin a machine readable form. Our system understands that the\nfull text of a record was removed only when the record is marked\nas deleted in the metadata of your repository. See\n[how to take down full text](#how-do-I-notify-CORE-to-take-down-full-text-content)\nfrom CORE in the related FAQ.\n"},{"slug":"how-do-I-notify-CORE-to-take-down-full-text-content","question":"How do I notify CORE to take down full text content?\n","answer":"If full text content appears in CORE but not in the\nhosting service your repository manager can take it down via the\n[CORE Repository Dashboard](~services/repository-dashboard)\nanytime without notifying us. Alternatively, you can use the\n[update or remove article form](/article-update).\n"},{"slug":"full-text-has-been-removed-but-metadata-still-visible","question":"The full text has been removed, but the metadata is still visible\nin CORE\n","answer":"It is a CORE policy to remove only the full text and not\nthe metadata. Only in limited cases - e.g. when a publication\ndid not happen - it is possible that the metadata can be removed.\nIn that case,[email us](~contact).\n"},{"slug":"why-metadata-is-still-visible","question":"I have removed an item from my repository, but the metadata are\nstill visible in CORE\n","answer":"In order for the metadata to be removed from CORE they need to be\nmarked as \"deleted/removed\" in the repository. If the metadata are\nmarked as \"restricted\" CORE will still display it.\n"}]}]},{"id":"membership","title":"Membership","updateDate":"Last updated 22.02.2024","caption":"Membership","items":[{"slug":"what-is-membership-of-CORE","question":"What is membership of CORE?\n","answer":"We founded CORE to provide free indexing, and discovery for institutions. \nInitially, we were funded to provide these tools, but much of our funding ended in July 2023.\nAs a result, we have created a membership model, with both free and paid membership. \nOur founding goal remains as before: we index any institutional repository. \nIf you register as a starting member, you can see a freely available dashboard that shows \nuseful information about your repository. We have added optional paid tools \nthat assist in analytics and compliance.\n"},{"slug":"is-CORE-paid-membership-worth-it","question":"Is CORE paid membership worth it?\n","answer":"By joining CORE you are supporting the open research community. \nMoreover, we believe that our paid membership provides tools that \nsave your institution time and money. It enables you to check automatically \nwhat would otherwise have to be done by hand, for example finding copies of\npapers by a member of your institution that were deposited in another repository \n(what we call the “cress-repository check”). Finally, as a paying member,\nwe provide anyone from your institution with fast API access to the full \nCORE dataset for text and data-mining (TDM) purposes.\n"},{"slug":"Your-membership-prices-look-very-high-for-developing-countries","question":"Your membership prices look very high for low-income countries\n","answer":"Our aim is to make membership available for the widest range of institutions. \nAccordingly, we have set three tiers of membership, using the widely accepted\n[World Bank criteria](https://datahelpdesk.worldbank.org/knowledgebase/articles/906519-world-bank-country-and-lending-groups) \nfor low- and middle-income countries. Our aim is to make membership available to all,\nbecause the more institutions who join, the better the service for all members: \nspecifically, we can check other repositories for relevant content to your institution, wherever it appears.\n"},{"slug":"can-you-help-us","question":"We don’t have enough technical knowledge to use the dashboard. Can you help us? \n","answer":"Many institutions don’t have the staff or the knowledge to manage their repository effectively. \nFor sustaining members, we provide a free repository health check every year. \nWe go through all the results from our automatic checks and show you how to fix them. \nIn other words, we provide a kind of out-sourced technical resource for you.\n"},{"slug":"do-I-need-to-be-a-member-of-CORE-to-use-the-Recommender-tool?","question":"Do I need to be a member of CORE to use the Recommender tool?\n","answer":"Both the Recommender and the Discovery tools are free of charge for any institution \nthat provides their data for indexing. They are both benefits of the free starting membership.\n"},{"slug":"why-do-we-need-compliance-tools","question":"We don’t use our repository to track compliance, so why do we need compliance tools?\n","answer":"For many countries, including the United States, institutions may not track compliant\nacross the institution. However, individual faculties and departments want to ensure \nthat their publications are comipliant with federal and with funder mandates. \nMembership of CORE enables you to identify that a paper has been deposited, \neven if it was not deposited in your local repository.\n"}]},{"id":"dashboard","title":"Dashboard","updateDate":"Last updated 22.02.2024","caption":"Dashboard","items":[{"slug":"what-is-the-CORE-dashboard","question":"What is the CORE dashboard?\n","answer":"For any institution, we provide a dashboard that enables them to see their \nrepository from the outside - the way that any external service sees them.\nWe give you statistics about the number of items indexed, how many of \nthem are full text, and the proportion of content that has a DOI identifier. \nThe dashboard is free to access for any institution who signs up for free starting membership.\n"},{"slug":"why-can’t-I-see-my-dashboard","question":"Why can’t I see my dashboard?\n","answer":"You can only see the dashboard for your organisation if you have signed up as a member. \nBecoming a starting member is free of charge for any institution that provides content for CORE to index. \nSimply contact the administrator at [XX@core.ac.uk]() to be sent an invitation to open an account.\n"},{"slug":"how-does-CORE-help-my-institution-with-compliance","question":"How does CORE help my institution with compliance?\n","answer":"Open access articles are free to access, but the publisher may not maintain \na freely available copy for researchers to access. It makes sense for researchers\nto self-archive their content. The author (or the institution) posts the article in \na repository, typically the institutional repository of the university where they work. \nHowever, in many countries, funding requirements are not only that the article \nshould be available open access, but that the article should be available within a certain \ntime period after acceptance. For the UK REF 2021, this time period, known as the deposit delay, was 90 days.\n\nThis introduces a reporting requirement for any institution that wants to be compliant with funder mandates: \nit is necessary to demonstrate that articles are compliant, that is, available open access and deposited within the correct time frame.\n\nFor every institutional repository where CORE indexes content, we try to assist you with compliance,\nidentifying the date of deposit wherever possible, as well as the date of publication.\n"},{"slug":"how-can-I-track-the-date-of-deposit-for-my-content","question":"How can I track the date of deposit for my content?\n","answer":"The date of deposit is increasingly added as a metadata field when content is \nuploaded to repositories. [RIOXX](https://rioxx.net), for example, is a metadata \nprotocol that enables metadata to be shared across repositories, particularly \ndate of deposit metadata. If all institutions make the date of deposit information available, \nCORE can provide a service for every repository by finding compliant versions of papers in other repositories.\n"},{"slug":"why-do-I-need-CORE","question":"I have a CRIS system, so why do I need CORE?\n","answer":"Simply put, any CRIS system (Current Research Information System) works for an individual institution. \nAlthough it can often show compliance for papers within that institution, \na CRIS system (or an individual repository) cannot find duplicate copies of articles \nthat were deposited in another institution, for example if a paper has a co-author\nfrom Sheffield when the main author is based at Leeds. CORE is unique in indexing \nrepositories from around the world, and can identify duplicate copies of papers. \nAs a result, CORE and CRIS systems are complements, not substitutes, for each other.\n"}]},{"id":"services","title":"CORE services","updateDate":"Last updated 22.02.2024","caption":"Services","items":[{"slug":"how-do-I-register-for-an-API-key","question":"How do I register for an API key?\n","answer":"Use the [registration form](/api-keys/register) to retrieve\nyour personal access key for the CORE API.\n"},{"slug":"can-I-use-the-CORE-API-in-a-project","question":"Can I use the CORE API in a project?\n","answer":"If you plan to use the CORE API we kindly ask the following:\n- attribute CORE by including in your website\n [this snippet](#powered-by-CORE-snippet),\n- send us [an email](~contact) with a brief summary on\n how you are using the CORE API,\n- grant us permission to present this summary to our funders and/or\n display it on our website,\n- allow us to list your company’s name, url and logo on our\n [website](~endorsements).\n"},{"slug":"does-CORE-offer-a-higher-download-quota-of-the-CORE-API","question":"Does CORE offer a higher download quota of the CORE API?\n","answer":"Yes, this is possible but there is usually a cost associated with it.\nPlease [email us](~contact) the name of your\ncompany or organisation, business entity, the number of requests you\nestimate to send and how often you will send them and we will get\nback to your with a quote.\n"},{"slug":"can-I-use-the-CORE-API-for-commercial-purposes","question":"Can I use the CORE API for commercial purposes?\n","answer":"Yes, you can use the CORE API for commercial purposes, (Terms \u0026 Conditions) apply.\nWe provide 30 Day Free Trial for Institution and Enterprise.\nWe will ask you for your circumstances during the registration process and we might\ncontact you afterwards to clarify any points and assess your eligibility for a free licence.\nIf your circumstances change, please let us know.\n"},{"slug":"rate-limits","question":"Rate limits\n","answer":"CORE API is free and does not require registration, subject to our [rate limits](https://api.core.ac.uk/docs/v3#section/Rate-limits).

By doing so, an output deposited late in repository A\ncould be technically compliant provided that it was deposited within\nthe timeframe at repository B, i.e. the earliest deposit date\nirrespective of the repository could be used. However, for the time\nbeing, CORE agreed to supply the data to Research England and it will\nbe up the discretion of Research England to interpret the data.

By\nfollowing our recommendations CORE should have the same deposit date\nas the repository. The date you see in the CORE API is the date the\ndocument was last seen in your repository and imported to CORE.
