One condition of all CC licenses is attribution: crediting the author and noting the source and the license. Generally speaking, attribution must reasonably include all relevant information supplied by the licensor. Because each use case is different, you can decide what form of attribution is most suitable for your specific situation. The following examples are intended to illustrate what typical prudent practices look like. We expect community norms and expectations to evolve with time, and will adapt this guide accordingly. In addition to attribution, there are also <a rel="nofollow" class="external text" href="https://wiki.creativecommons.org/wiki/Considerations_for_licensors_and_licensees#Considerations_for_licensees%7Cother">things to consider as a licensor or a licensee</a>.

attribution include the <b>T</b>itle, <b>A</b>uthor, <b>S</b>ource, and <b>L</b>icense. This is true whether you’re sharing the work as-is or if you have made an adaptation. To remember these attribution elements, it’s helpful to think of the acronym: <b>TASL</b>.</p> <p>Let’s now go through <b>TASL</b> — we will explain each element in more detail:</p> <p><b>Title</b>: What is the name of the work?</p> <dl> <dd>If a title was provided for the work, include it as a part of the attribution. Sometimes a title is not provided; in that case, there’s no need to mention the title.</dd> </dl> <dl> <dd>The inclusion of title is a requirement of all CC licenses version 3.0 or earlier, and it is optional for the 4.0 suites. See <a rel="nofollow" class="external text" href="https://wiki.creativecommons.org/wiki/Recommended_practices_for_attribution#License_details">License details</a>.</dd> </dl> <p><b>Author</b>: Who allows you to use the work?</p> <dl> <dd>We often use “author” as a shorthand when we are, legally speaking, referring to the “licensor” (a.k.a., the “copyright holder” or “rightsholder”). This is because, in most CC-licensed works, the licensor is the same person or entity as the author. When an author is licensing their work under a CC license, and has made their name available, include the author’s name as a component in your attribution. Sometimes, the licensor may want you to give credit to some other entity, like a company or institution, or the licensor may want to be credited by a pseudonym instead of their real name. In rare cases, the licensor may not want to be attributed at all. In all of these cases, do what the licensor requests.</dd> </dl> <dl> <dd>Sometimes, the author will also provide a copyright notice, which consists of the copyright symbol, year of publication, and the name of the author/licensor. Include the copyright notice as a part of your attribution if such information is provided.</dd> </dl> <p><b>Source</b>: Where can people find the work?</p> <dl> <dd>Please make it possible for future users to find the source of the material by including a URL or hyperlink where the work resides. This often is where you found the work. If you found it somewhere other than the original site, try to include information about the original site where the work was first shared publicly. It is also better to use the original URL instead of a shortened link, whether you are hyperlinking or printing out the entire URL.</dd> </dl> <p><b>License</b>: How can you use the work?</p> <dl> <dd>You must specify which CC license was applied to the work you are reusing. Each of the six different CC licenses come with distinct requirements for re-use. We recommend that you name and provide a link to the license, e.g., <a rel="nofollow" class="external text" href="http://creativecommons.org/licenses/by/4.0">CC BY 4.0</a> (<a rel="nofollow" class="external free" href="http://creativecommons.org/licenses/by/4.0">http://creativecommons.org/licenses/by/4.0</a>) for a work licensed under CC BY 4.0.</dd> </dl> <dl> <dd>Consider also including the “disclaimer of warranties,” which clarifies that the author makes no representations or warranties about the non-infringement or absence of other defects concerning the CC-licensed work. In plain English, this means that the users will use the work at their own risk.</dd> </dl> <dl> <dd>To sum up, if the licensor has provided any information related to TASL, consider including them in your attribution. We also recommend providing links to the Title, Author, Source, and License, where possible, so future users can easily access the information they need on a work and the license terms.</dd> </dl> <hr /> <h3><span class="mw-headline" id="Reasonable_attribution">Reasonable attribution</span></h3> <p>The CC licenses ask you to be reasonable:</p> <dl> <dd> <div style="padding: 1em; margin-bottom: 1em; border: 1px; background-color: #eee; width: 90%;">You may satisfy the attribution requirement in any reasonable manner based on the medium, means and context in which the Licensed Material is used.

For media such as offline materials, video, audio, and images, consider publishing a web page with attribution information. For example, on a webpage featuring your audio recording, provide a credit list of material you used that adheres to best practices above. Doing so allows not only your material, but the materials you attribute, to be found by search engines and other web discovery tools. If possible within the medium, make the Author, Source, and License links the user can follow.</p> <dl> <dd> <div style="padding: 1em; margin-bottom: 1em; border: 1px; background-color: #eee; width: 65%;"><b>Example:</b><br /> This video features the song <a rel="nofollow" class="external text" href="http://ccmixter.org/media/files/victor/6374">"Desaprendere (Treatment)"</a> by <a rel="nofollow" class="external text" href="http://fourstones.net/">fourstones</a>, available under a Creative Commons <a rel="nofollow" class="external text" href="http://creativecommons.org/licenses/by-nc/2.5/">Attribution-Noncommercial 2.5 license</a>.</div> </dd> </dl> <hr /> <h2><span class="mw-headline" id="Citing_public_domain_materials">Citing public domain materials</span></h2> <p>Although attribution is not a legal obligation under <a rel="nofollow" class="external text" href="https://creativecommons.org/share-your-work/public-domain/cc0/">CC0 dedication</a>’s or <a rel="nofollow" class="external text" href="https://creativecommons.org/share-your-work/public-domain/pdm/">CC Public Domain Mark</a>’s licensing terms, we recommend that you consider including information about the hosting institution for public domain materials when it is reasonable to do so. Citing public domain works in this way not only encourages institutions to digitize and share more public domain materials in their physical collections, but also empowers users to easily locate the original source.</p> <p>Here is an example of citing the source of a public domain image. The following public domain image is digitized and hosted by the Rijksmuseum (the national museum of the Netherlands). The Rijksmuseum has applied a CC0 dedication to the image.</p> <dl> <dd><a href="/wiki/File:Attributing_the_milkmaid.png" class="image"><img alt="Attributing the milkmaid.png" src="/images/thumb/7/7d/Attributing_the_milkmaid.png/300px-Attributing_the_milkmaid.png" width="300" height="402" srcset="/images/thumb/7/7d/Attributing_the_milkmaid.png/450px-Attributing_the_milkmaid.png 1.5x, /images/thumb/7/7d/Attributing_the_milkmaid.png/600px-Attributing_the_milkmaid.png 2x" /></a></dd> </dl> <p>You may provide credit in the following format:</p> <dl> <dd> <div style="padding: 1em; margin-bottom: 1em; border: 1px; background-color: #eee; width: 65%;">“<a rel="nofollow" class="external text" href="http://hdl.handle.net/10934/RM0001.COLLECT.6417">The Milkmaid</a>” by Vermeer.

These practices are not always contrary to the Creative Commons licensing terms, but they often make it more challenging for users to find the original source and/or author.</p> <p><b>Attribute in alt text</b></p> <dl> <dd>Alt text is intended to provide accessible information about visual materials for users with cognitive disabilities or visual impairment. Using this field for licensing information makes browsing difficult for those users.</dd> </dl> <p><b>Attribute in metadata fields only</b></p> <dl> <dd>While it is great to include attribution in metadata fields (such as EXIF for images), in most cases this is not the only place to include attribution information. This is because many users are likely not aware of, and will never see, attribution information included in metadata.</dd> </dl> <p><b>Credit authors by names other than the ones they have selected</b></p> <dl> <dd>Many people believe that attribution must be given to the real name of the author of a work, but this is not the case — always give attribution to the name the author has specified, even if it is a pseudonym. If the author does not give a name or explicitly requests to be anonymous, you must give the other attribution information (i.e., “T” and “SL” from “TASL”) without crediting the author.</dd> </dl> <p><b>Credit a site (or Creative Commons itself!) instead of the author</b></p> <dl> <dd>Unless an author specifically requests users to only credit a site, crediting the site where you have found the material cannot substitute crediting the author. An author may have uploaded material to a site under a CC license, but in most cases, the copyright is still held by the author, and it is the copyright holder who needs to be credited. For example, many photos sourced from Wikimedia Commons are attributed to Wikimedia when they must be attributed to the authors.</dd> </dl>   </div>  </div> <div class="printfooter"> Retrieved from "<a dir="ltr" href="https://wiki.creativecommons.org/index.php?title=Recommended_practices_for_attribution&oldid=117872">https://wiki.creativecommons.org/index.php?title=Recommended_practices_for_attribution&oldid=117872</a>" </div> <div id="catlinks" class="catlinks" data-mw="interface"><div id="mw-normal-catlinks" class="mw-normal-catlinks"><a href="/wiki/Special:Categories" title="Special:Categories">Categories</a>: <ul><li><a href="/wiki/Category:Marking" title="Category:Marking">Marking</a></li><li><a href="/wiki/Category:Licensing" title="Category:Licensing">Licensing</a></li><li><a href="/wiki/Category:Community" title="Category:Community">Community</a></li><li><a href="/wiki/Category:Media" title="Category:Media">Media</a></li><li><a href="/wiki/Category:HOWTO" title="Category:HOWTO">HOWTO</a></li><li><a href="/wiki/Category:Guide" title="Category:Guide">Guide</a></li><li><a href="/wiki/Category:Best_Practice" title="Category:Best Practice">Best Practice</a></li></ul></div></div> <div class="visualClear"></div> </div> </div> <div id="mw-navigation"> <h2>Navigation menu</h2> <div id="mw-head"> <div id="p-personal" role="navigation" class="" aria-labelledby="p-personal-label"> <h3 id="p-personal-label">Personal tools</h3> <ul> <li id="pt-login"><a href="/index.php?title=Special:UserLogin&returnto=Recommended+practices+for+attribution" title="You are encouraged to log in; however, it is not mandatory [o]" accesskey="o">Log in</a></li> </ul> </div> <div id="left-navigation"> <div id="p-namespaces" role="navigation" class="vectorTabs" aria-labelledby="p-namespaces-label"> <h3 id="p-namespaces-label">Namespaces</h3> <ul> <li id="ca-nstab-main" class="selected"><span><a href="/wiki/Recommended_practices_for_attribution" title="View the content page [c]" accesskey="c">Page</a></span></li> <li id="ca-talk"><span><a href="/wiki/Talk:Recommended_practices_for_attribution" rel="discussion" title="Discussion about the content page [t]" accesskey="t">Discussion</a></span></li> </ul> </div> <div id="p-variants" role="navigation" class="vectorMenu emptyPortlet" aria-labelledby="p-variants-label"> <h3 id="p-variants-label"> <span>Variants</span> </h3> <div class="menu"> <ul> </ul> </div> </div> </div> <div id="right-navigation"> <div id="p-views" role="navigation" class="vectorTabs" aria-labelledby="p-views-label"> <h3 id="p-views-label">Views</h3> <ul> <li id="ca-view" class="selected"><span><a href="/wiki/Recommended_practices_for_attribution">Read</a></span></li> <li id="ca-viewsource"><span><a href="/index.php?title=Recommended_practices_for_attribution&action=edit" title="This page is protected.
