LibraryThing is asocial catalogingweb application for storing and sharing book catalogs and various types of bookmetadata. It is used by authors, individuals, libraries, and publishers.
Based inPortland, Maine,[1] LibraryThing was developed by Tim Spalding and went live on August 29, 2005, on afreemium subscriber business model, because "it was important to have customers, not an 'audience' we sell to advertisers." They focused instead on making a series of products for academic libraries. Motivated by the cataloguing opportunities and financial challenges presented by the COVID-19 pandemic, the service went "free to all" on March 8, 2020, while maintaining a promise never to use advertising on registered users.[2] As of February 2021,[update] it has 2,600,000 users and more than 155 million books catalogued,[3] drawing data from Amazon and from thousands of libraries that use theZ39.50 cataloguing protocol.
The primary feature of LibraryThing (LT) is the cataloging of books, movies, music and other media by importing data from libraries throughZ39.50 connections and from sixAmazon.com stores. Library sources supplyDublin Core andMARC records to LT; users can import information from over 2000 libraries, including theBritish Library,Canadian National Catalogue,Library of Congress,National Library of Australia, andYale University.[4] Should a record not be available from any of these sources, it is also possible to input the book information manually via a blank form.[5]
Each work may comprise different editions, translations, printings, audio versions, etc. Members are encouraged to add publicly visible reviews, descriptions, Common Knowledge and other information about a work; ratings, collections, and tags help categorization. Discussion in the forums is also encouraged.
Items are classified using the Melvil Decimal System, based on the out-of-copyright 1922 edition of theDewey Decimal Classification with modifications for standard spelling of division names (as opposed to the original names, which were spelled in accordance with Dewey'sadvocated spelling reforms), and modernised terminology.[6]
LibraryThing's social features have been compared to bookmark managerDel.icio.us[7] and the collaborative music serviceLast.fm.[8] Similar book cataloging sites includeaNobii,BookLikes,Goodreads,Libib,Shelfari (now merged with Goodreads), and weRead.[9]
In 2016, LibraryThing launched TinyCat, anOPAC designed for the cataloging and circulation of libraries of up to 20,000 items.[10] TinyCat is marketed towards small independent libraries, such as schools, community centers, religious institutions, and academic departments, as well as individuals.[11]
LibraryThing is majority owned by founder Tim Spalding.[12] Online booksellerAbeBooks bought a 40% share in LibraryThing in May 2006 for an undisclosed sum. AbeBooks became a subsidiary of Amazon in 2008.[13] In January 2009,Cambridge Information Group acquired a minority stake in LibraryThing, and their subsidiaryBowker became the official distributor to libraries.[12]
At the end of June 2006, LibraryThing was subject to theSlashdot effect from aWall Street Journal article.[14] The site's developers added servers to compensate for the increased traffic. In December of the same year, the site received yet more attention fromSlashdot over its UnSuggester feature, which draws suggestions from books least likely to appear in the same catalog as a given book.[15]
