The '''Open Publication Distribution System''' (OPDS) Catalog format is a [[Web syndication|syndication]] format for [[electronic publication]]s based on [[Atom (standard)|Atom]] and [[HTTP]]. OPDS Catalogs enable the aggregation, distribution, discovery, and acquisition of electronic publications. OPDS Catalogs use existing or emergent [[open standard]]s and conventions, with a priority on simplicity.<ref>{{Citation | date = 27 June 2011 | publisher = The Open Internet archive | url = http://opds-spec.org/specs/opds-catalog-1-1-20110627/ | title = OPDS Spec | contribution = OPDS Spec 1.1 | accessdate = 2013‐5‐7 | type = technical specification}}.</ref>

Retrieved May 5, 2013.</ref>, the company behind [[Lexcycle Stanza|Stanza]], an [[E-Book|eBook reader application]] for [[iOS]].

==OPDS Catalogs==

Dozens of OPDS catalogs are available online, and in many different languages.<ref>{{cite web |url=http://wiki.mobileread.com/wiki/OPDS#Online_OPDS_Catalogs |title=Online OPDS Catalogs |publisher=MobileRead Wiki|date= |accessdate=2011-05-19}}</ref>.

Many users of OPDS also create their own OPDS catalog, as a way to access their ebooks from any device.<ref>{{cite web |url=http://wiki.mobileread.com/wiki/OPDS#OPDS_Catalog_Generation |title=OPDS Catalog Generation |publisher=MobileRead Wiki|date= |accessdate=2011-05-19}}</ref>.

Developers implementing an OPDS catalog usually use the Feedbooks catalog<ref>{{cite web |url=http://www.feedbooks.com/catalog.atom |title=Feedbooks OPDS Catalog |publisher=Feedbooks |date= |accessdate=2011-05-19}}</ref> as an example of a fully featured catalog. An OPDS validator is also available to test OPDS feeds.<ref>{{cite web |url=http://opds-validator.appspot.com/ |title=OPDS Validator |accessdate=2011-05-19}}</ref>.

==Comparison of OPDS clients==

In order to test client compatibility, a test catalog is available as a [[GitHub]] project.<ref>{{cite web |url=http://feedbooks.github.io/opds-test-catalog/ |title=OPDS Test Catalog |publisher=Feedbooks |date= |accessdate=2011-05-15}}</ref>.

Over a dozen OPDS clients are available on major platforms such as [[Android (operating system)|Android]], [[iOS]] and [[Microsoft Windows|Windows]].<ref>{{cite web |url=http://wiki.mobileread.com/wiki/OPDS#eBook_Reading_Software_Supporting_OPDS |title=eBook Reading Software Supporting OPDS |publisher=MobileRead Wiki |date= |accessdate=2011-05-15}}</ref>.

This is a comparison for some of these clients, based on the results published for the test catalog.<ref>{{cite web |url=https://docs.google.com/spreadsheet/ccc?key=0AiWt3tA8qtyMdFpkZ0lxV011MXV6X3JJRFUxa050SHc |title=OPDS clients compatibility |date= |accessdate=2011-05-17}}</ref>.
