Abstract

If one follows any of the major cataloging or library blogs these days, it is obvious that the topic of FRBR (Functional Requirements for Bibliographic Records) has increasingly become one of major significance for the library community. What began as a proposed conceptual entity-relationship model for improving the structure of bibliographic records has become a hotly debated topic with many tangled threads that have implications not just for cataloging but for many aspects of libraries and librarianship. In the fall of 2005, the Perseus Project experimented with creating a FRBRized catalog for its current online classics collection, a collection that consists of several hundred classical texts in Greek and Latin as well as reference works and scholarly commentaries regarding these works. In the last two years, with funding from the Mellon Foundation, Perseus has amassed and digitized a growing collection of classical texts (some as image books on our own servers that will eventually be made available through Fedora), and some available through the Open Content Alliance (OCA)2, and created FRBRized cataloging data for these texts. This work was done largely as an experiment to see the potential of the FRBR model for creating a specialized catalog for classics.
Our catalog should not be called a FRBR catalog perhaps, but instead a "FRBR Inspired catalog." As such our main goal has been "practical findability," we are seeking to support the four identified user tasks of the FRBR model, or to "Search, Identify, Select, and Obtain," rather than to create a FRBR catalog, per se. By encoding as much information as possible in the MODS and MADS records we have created, we believe that useful searching will be supported, that by using unique identifiers for works and authors users will be able to identify that the entity they have located is the desired one, that by encoding expression level information (such as the language of the work, the translator, etc) users will be able to select which expression of a work they are interested in, and that by supplying links to different online manifestations that users will be able to obtain access to a digital copy of a work. This white paper will discuss previous and current efforts by the Perseus Project in creating a FRBRized catalog, including the cataloging workflow, lessons learned during the process and will also seek to place this work in the larger context of research regarding FRBR, cataloging, Library 2.0 and the Semantic Web, and the growing importance of the FRBR model in the face of growing million book digital libraries.
