Karen Coyle outlines a vision for the future of library catalogs from 1990 to 2020. She sees library catalogs evolving from isolated systems only connected to other libraries, to being fully integrated parts of the broader information landscape. Formats like MARC and standards like RDA will incorporate rigorous machine-readable structures like RDF, allowing library data to be more widely shared and reused across bibliographic applications on the web. This will create a more integrated bibliographic universe with stronger connections between documents, bibliographies, and library catalogs.

1. Catalog 2.0 Karen Coyle http://www.kcoyle.net

2. Timeline 1990 Exchange of data between libraries 2000 Use of the web to interact with users 2010 Exchange of library data with Web services 2020 Library catalogs are no longer a destination but an integral part of the information space …

4. The user begins with a search on Google Books…

5. … and is informed that the local public library has the book.

6. The library catalog can also link out to other resources….

7. … such as reviews.

9. Functional Requirements for Bibliographic Records (FRBR) FRBR provides a basic structure for bibliographic description.

10. Creators/producers

11. Topics

12. RDA is a textual standard

13. The resulting cataloging is similar to that created for card catalogs

14. RDA includes some lists of terms that should not be part of the cataloging rules themselves. They need to be able to be used outside of RDA and they need to be able to grow.

15. These same terms could be expressed in a machine-readable web format.

16. Information can be given about each term, with broader and narrower concepts.

17. While a human will see an eye-readable display, a machine accessing that same term will be given the data in a format that it can use programmatically.

18. The context within the vocabulary is included

19. New terms can be added at any time, without requiring a change to the standard itself.

20. An entry for a term can include definitions, synonyms, or any other information included in the design of the vocabulary software.

21. All of this information about the term becomes available to programs, and might be used to aid input or to inform catalog users.

22. Dublin Core + FRBR + RDF The Dublin Core community is already experimenting with FRBR, showing how a shared view of the deep structure of bibliographic data can lead to compatibility between standards.

24. Article 1. Smith, John. “Use of Dublin core with FRBR” New York, London, 2007 Library Catalog <bb:description> <bb:statement <bb:propertyURI=“bibPerson” bb:propertyURI=“&RDA;author” bb:valueURI=“&33987687” bb:valueDisplay=“Smith, John” … etc. …. /> One day, the bibliographic citation in a document may be able to make use of the same structure that underlies the library catalog. This will make linking more accurate between different uses of the same bibliographic entry.

27. This becomes the norm
