Abstract

After a short outline of problems, possibilities and difficulties of systematic information retrieval on the Internet and a description of efforts for development in this area, a specification of the terminology for this report is required. Although the process of retrieval is generally seen as an iterative process of browsing and information retrieval and several important services on the net have taken this fact into consideration, the emphasis of this report lays on the general retrieval tools for the whole of Internet. In order to be able to evaluate the differences, possibilities and restrictions of the different services it is necessary to begin with organizing the existing varieties in a typological/ taxonomical survey. The possibilities and weaknesses will be briefly compared and described for the most important services in the categories robot-based WWW-catalogues of different types, list- or form-based catalogues and simultaneous or collected search services respectively. It will however for different reasons not be possible to rank them in order of "best" services. Still more important are the weaknesses and problems common for all attempts of indexing the Internet. The problems of the quality of the input, the technical performance and the general problem of indexing virtual hypertext are shown to be at least as difficult as the different aspects of harvesting, indexing and information retrieval. Some of the attempts made in the area of further development of retrieval services will be mentioned in relation to descriptions of the contents of documents and standardization efforts. Internet harvesting and indexing technology and retrieval software is thoroughly reviewed. Details about all services and software are listed in analytical forms in Annex 1-3.

Abstract

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.
