OPDS catalogs enable the aggregation, distribution, discovery, and acquisition of electronic publications. OPDS catalogs use existing or emergent open standards and conventions, with a priority on simplicity. The Open Publication Distribution System specification is prepared by an informal grouping of partners, combining Internet Archive, O'Reilly Media, Feedbooks, OLPC, and others. HistoryOPDS is based on the initial work done by Lexcycle, the company behind Stanza,[1] an eBook reader application for iOS.{{citation needed|date=December 2017}} All revisions of the specification were produced by an informal group organized around an open mailing list.[2]
OPDS softwareMany e-readers or e-book reading applications support importing books from an OPDS catalog. E-book management applications such as Calibre also often include OPDS server software to make an e-book collection available through an OPDS catalog.

OPDS catalogsDozens of OPDS catalogs are available online, and in many different languages.[9] Many users of OPDS also create their own OPDS catalog, as a way to access their ebooks from any device.[10] Developers implementing an OPDS catalog usually use the Feedbooks catalog[11] as an example of a fully featured catalog. An OPDS validator is also available to test OPDS feeds.[12] {{Clear}}References1. ^{{cite mailing list |url=http://groups.google.com/d/topic/openpub/Vr8FI7gIKHg/discussion |title=Project Goals |date=April 9, 2009 |accessdate=May 5, 2013 |mailing-list=Open Publication Distribution System |last=Fahlgren |first=Keith |via=Google Groups }} 2. ^{{cite web |url=http://groups.google.com/group/openpub |title=Open Publication Distribution System |website=Google Groups |access-date=May 5, 2013 }} 3. ^{{cite web |url=http://opds-spec.org/specs/ |title=Specifications |website=Open Publication Distribution System: Official Specification & Blog |access-date=December 4, 2017 }} 4. ^{{cite web |url=https://specs.opds.io/opds-0.9.html |title=OPDS Catalog 0.9 |access-date=May 5, 2013 }} 5. ^{{cite web |url=https://specs.opds.io/opds-1.0.html |title=OPDS Catalog 1.0 |access-date=May 5, 2013 }} 6. ^{{cite web |url=https://specs.opds.io/opds-1.1.html |title=OPDS Catalog 1.1 |access-date=May 5, 2013 }} 7. ^{{cite web |url=https://specs.opds.io/opds-1.2 |title=OPDS Catalog 1.2 |access-date=November 11, 2018 }} 8. ^{{cite web |url=https://drafts.opds.io/opds-2.0 |title=OPDS Catalog 2.0 |access-date=November 11, 2018 }} 9. ^{{cite web |url=http://wiki.mobileread.com/wiki/OPDS#Online_OPDS_Catalogs |title=Online OPDS Catalogs |publisher=MobileRead Wiki|date= |accessdate=2011-05-19}} 10. ^{{cite web |url=http://wiki.mobileread.com/wiki/OPDS#OPDS_Catalog_Generation |title=OPDS Catalog Generation |publisher=MobileRead Wiki|date= |accessdate=2011-05-19}} 11. ^{{cite web |url=http://www.feedbooks.com/catalog.atom |title=Feedbooks OPDS Catalog |publisher=Feedbooks |date= |accessdate=2011-05-19}} 12. ^{{cite web |url=https://opds-validator.appspot.com/ |title=OPDS Validator |accessdate=2011-05-19}} External linksOPDS standard
