The Perseus Catalog is an attempt to provide systematic catalog access to at least one online edition of every major Greek and Latin author (both surviving and fragmentary) from antiquity to 600 CE. Still a work in progress, the catalog currently includes 3,679 individual works (2,522 Greek and 1,247 Latin), with over 11,000 links to online versions of these works (6,419 in Google Books, 5,098 to the Internet Archive, 593 to the Hathi Trust). The Perseus interface now includes links to the Perseus Catalog from the main navigation bar, and also from within the majority of texts in the Greco-Roman collection.
The metadata contained within the catalog has utilized the MODS and MADS standards developed by the Library of Congress as well as the Canonical Text Services and CTS-URN protocols developed by the Homer Multitext Project. The Perseus catalog interface uses the open source Blacklight Project interface and Apache Solr. Stable, linkable canonical URIs have been provided for all textgroups, works, editions and translations in the Catalog for both HTML and ATOM output formats. The ATOM output format provides access to the source CTS, MODS and MADS metadata for the catalog records. Subsequent releases will make all catalog data available as RDF triples.
Other major plans for the future of the catalog include not only the addition of more authors and works as well as links to online versions but also to open up the catalog to contributions from users. Currently the catalog does not include any user contribution or social features other than standard email contact information but the goal is to soon support the creation of user accounts and the contribution of recommendations, corrections and or new metadata.
