We are eager to work with booksellers, libraries, and library vendors to integrate Talpa into your application. For more information, email tim@librarything.com.</p> <h2>LibraryThing APIs</h2> <p>Our <a href="/developer/documentation/thingapis">Lightweight APIs</a> will primarily interest developers in the library and book world.</p> <p>LibraryThing does not currently offer an API for members' books. (Members who want copies of their own data should visit <a href="more/import">Import/Export</a>.) This is due to data-licensing restrictions from external providers, especially Amazon. We are working on a solution to deliver the data we can, transforming licensed data to free versions where possible.</p> <p>LibraryThing does not offer bibliographic data. For high-quality bibliographic data, such as titles, authors, publication dates, covers, and summaries, please visit <a href="https://bowkerbookdata.proquest.com">Bowker Book Data</a>.</p> <h2>LibraryThing Feeds</h2> <p>LibraryThing offers several <a href="/services/feeds/guide">XML data feeds</a> to select libraries and bookstores, as well as to qualified academic researchers.</p><a name="bottom"></a></div></main><div id="helpdrawer" data-helpurl="https%3A%2F%2Fwiki.librarything.com%2Fapi.php%3Fformat%3Djson%26action%3Dparse%26origin%3D%2A%26servedby%3D1%26page%3DHelpThing%3ADeveloper_controller" data-baseurl="https%3A%2F%2Fwiki.librarything.com%2Fapi.php%3Fformat%3Djson%26action%3Dparse%26origin%3D%2A%26servedby%3D1%26page%3D" ><a id="hdclose" href="#" onclick="lt.helpdrawer_close();return false;" class="greylink" title="Close Help"><i class="fa-solid fa-circle-xmark"></i></a><div id="hdc"></div></div><footer class="lt2_footer bluelink"><div class="lt2_footer_links controlitems"><a href="#" id="stylepicker_switch" onclick="lt.stylepick_switch();return false;"><i class="fas fa-text-size"></i> Change Style</a><a class="footer_displaymode" data-dmode="0" title="Toggle Desktop Version" href="#" onclick="return lt.desktopversion();"><span id="footer_desktop"><i class="fas fa-desktop"></i>Desktop View</span><span id="footer_mobile"><i class="far fa-mobile-alt"></i>Mobile View</span></a></div><div class="lt2_footer_links"><a href="/" target="_top">Home</a><a href="/about" target="_top">About</a><a href="/contact" target="_top">Contact</a><a href="/privacy" target="_top">Privacy</a><a href="https://wiki.librarything.com/index.php/HelpThing:Developer_controller" target="_top">Help</a></div><div class="lt2_footer_links small"><a href="https://blog.librarything.com" target="_blank">Blog</a><a href="https://wiki.librarything.com">WikiThing</a><a href="/commonknowledge/">Common Knowledge</a><a href="/ner">Early Reviewers</a><a href="/legacylibraries">Legacy Libraries</a><a href="/local">Local</a><a href="/developer">APIs</a><a href="https://www.librarycat.org/">TinyCat <i class="lti lti-tinycat"></i></a></div></footer><div id="lt2_stylepicker"><div id="lt2_stylepicker_close" onclick="lt.stylepick_switch();"><i aria-label="Close" class="fas fa-times"></i></div><a href="#" title="verdant_14" data-style="verdant_14" onclick="lt.stylepick('verdant_14');return false;" class="stylepicker_item alwaysblue selected ">Verdana Standard</a><a href="#" title="verdant_12" data-style="verdant_12" onclick="lt.stylepick('verdant_12');return false;" class="stylepicker_item alwaysblue ">Verdana Small</a><a href="#" title="verdant_tight_12" data-style="verdant_tight_12" onclick="lt.stylepick('verdant_tight_12');return false;" class="stylepicker_item alwaysblue ">The Lorax</a><a href="#" title="system_14" data-style="system_14" onclick="lt.stylepick('system_14');return false;" class="stylepicker_item alwaysblue ">System Standard</a><a href="#" title="system_15" data-style="system_15" onclick="lt.stylepick('system_15');return false;" class="stylepicker_item alwaysblue ">System Large</a><a href="#" title="georgia_14" data-style="georgia_14" onclick="lt.stylepick('georgia_14');return false;" class="stylepicker_item alwaysblue ">Georgia</a><a href="#" title="system_large" data-style="system_large" onclick="lt.stylepick('system_large');return false;" class="stylepicker_item alwaysblue ">Large Text</a><a href="#" title="atkinson_16" data-style="atkinson_16" onclick="lt.stylepick('atkinson_16');return false;" class="stylepicker_item alwaysblue ">Atkinson</a></div><div id="gdpr_notice" class=""><button class="btn" id="gdpr_closebutton" onclick="gdpr_notice_clicked();return false;">I Agree</button><div id="gdpr_content">This site uses cookies to deliver our services, improve performance, for analytics, and (if not signed in) for advertising.
