  1. Organizing Internet Resources

  2. OCLC’s Internet Cataloging Project --funded by the Department of Education -- from October 1, 1994 to March 31, 1996. -- Participating libraries will identify, select, and catalog Internet accessible electronic information objects.

  3. OCLC’s Internet Cataloging Project This project was designed to: 1. facilitate the rapid creation of a database of USMARC format bibliographic records for remotely accessible electronic files through a coordinated, cooperative nationwide effort involving OCLC, college and university libraries, and repositories of electronic information. -

  4. OCLC’s Internet Cataloging Project This project was designed to: 2. provide widespread access to this catalog of items via the OCLC Online Union Catalog, the OCLC FirstSearch system, and a specially created database with access to all Internet users. 3. complete the links between coded location and access data in the bibliographic records (USMARC field 856) and the objects themselves by facilitating automated file transfer to the user or other access methods. -

  5. OCLC’s Internet Cataloging Project Purposes: 1. There is a great deal of valuable information available through the Internet. 2. These resources need to be organized for accessibility. 3. Using existing library techniques and procedures and creating records for retrieval through existing online catalogs.

  6. OCLC’s Internet Cataloging Project Goals: 1. Build a national database of MARC records for selected Internet resources. 2. Provide access to this catalog via OCLC, FirstSearch, and the Internet itself. 3. Create a link between the 856 (location & access) field and the resources themselves.

  7. OCLC’s Internet Cataloging Project Useful URLs: 1. NetFirst:http://www.oclc.org/oclc/netfirst/ 2. Olson, Nancy (Ed.). (1997). “Cataloging Internet Resources: A Manual and Practical Guide.” 2nd ed. http://www.purl.org/oclc/cataloging-internet 3. PURL: http://purl.oclc.org 4. OCLC: http://www.oclc.org 5.http://www.oclc.org/oclc/research/projects/intercat.htm

  8. OCLC’s Internet Cataloging Project Cataloging Standards: 1. MARC format 2. AACR2R 3. All records need to include 856 field "Electronic Location and Access" field.

  9. Issues Related to Cataloging Internet Resources 1. Ownership vs. access 2. The role of AACR2 in networked environment 3. Interface issues 4. Collection development for Internet resources 5. Workflow 6. Shift of responsibilities 7. Policy or criteria for selecting Internet resources 8. Training, etc.

  10. InterCat (purl.org/net/intercat) InterCat is an experimental, proof-of-concept database initiated during the 1994-1996 U.S. Department of Education-funded project, “Building a Catalog of Internet Resources.” January 2000 92,000 records 1997 14,813 records 1996 5,928 records 1995 2,550 records

  11. MARC Systems Primary purpose: automate bibliographic record processing Standard: MARC - AACR2 MARC Record Processing System input: MARC editor with embedded AACR2 MARC database management software for file creation and indexing Z39.50 retrieval for OPAC display MARC only works for library environment

  12. Markup Systems TEI and SGML Purpose: act as title page for electronic documents Standard: AACR2 SGML software for processing editing software for inputting Generalized file management system SGML publishing software for output and converters for Web display

  13. Markup Systems Dublin Core & HTML, XML Purpose: Resource Description on Web Standard: Dublin Core HTML, XML tag sets Generic Web Tools for Processing Web browser input forms Web servers and indexers for file management Web browser for retrieval and display XML is for Web environment.

  14. Metadata and the Internet March 1995. OCLC sponsored a Metadata workshop Goal: develop an agreed upon set of elements that could be used to describe virtually any type of electronic document. This set of descriptive elements would complement other methods of describing Internet resources (cataloging records, automatic indexing), not to replace them. These descriptive elements are referred to as metadata (data about data).

  15. Metadata and the Internet Metadata will act as a surrogate for the document itself, much in the same way a cataloging card acts as a representation of the book. Elements for the core descriptive set were chosen that can be expanded and extended to cover a variety of different Internet resources.

  16. Metadata and the Internet Fifteen core descriptive elements were chosen. These core elements were referred to as the Dublin Core: 1. Title 2. Author/Creator 3. Subject/Keywords 4. Description 5. Publisher 6. Other contributor

  17. Metadata and the Internet 7. Date 8. Resource Type 9. Format 10. Resource Identifier 11. Source 12. Language 13. Relation 14. Coverage 15. Rights Management

  18. Metadata and the Internet Metadata workshops and related events have taken place all over the world each year. Problems with Metadata

  19. Metadata and the Internet Additional information on Dublin Core: Dublin Core Homepage http://purl.org/metadata/dublin_core Matadate Editors: Dublin Core Metadata Template http://www.lub.lu.se/cgi-bin/nmdc.pl

  21. Metadata and the Internet Web Page Builder Iowa State University http://www.lib.iastate.edu/demo/cat/menu.html What will be retrieved is a list of Web resources displayed in a homepage format.

  22. Persistent URLs (PURLs) PURL: http://purl.oclc.org PURLs provide URL redirection PURLs are URLs in form and function Based on widely developed Internet standards: TCP/IP DNS HTTP URL

  25. Recent OCLC Project CORC--Cooperative Online Resource Catalog http://www.oclc.org/oclc/corc/index.htm CORC is a research project exploring the cooperative creation and sharing of metadata by libraries.

  26. Recent OCLC Project CORC is designed to help both libraries and OCLC to move more quickly in coping with the huge amount of materials becoming available on the World Wide Web.

  27. Recent OCLC Project CORC is a Web-based service being developed by OCLC in partnership with several hundred volunteer libraries. The databases and tools that compose CORC are designed to assist libraries inproviding their users with well-guided access to Web resources.

  28. Recent OCLC Project CORC offers four searchable databases: CORC Resource Record Database CORC Authority Database CORC Pathfinder Database Dewey Decimal Classification Database

  29. Recent OCLC Project CORC's tools are based on cutting edge technologies developed by OCLC and support: 1. Rapid, automation-assisted creation of resource records (i.e. bibliographic records). 2. Automatic assignment of suggested Dewey Decimal classification numbers and subclassification numbers. 3. Automatic assignment of suggested keywords for retrieval.

  30. Recent OCLC Project 4. Automated authority control. 5. Cooperative, automation-assisted maintenance of URL's in resource records. 6. Advanced tools for creating/editing digital pathfinders (HTML pages of narrative and links to resources).

  31. Recent OCLC Project With CORC, library staff can create, edit, import, and export: 1. Resource records (a record describing a resource - the same record can be presented in the user's choice of OCLC- MARC or Dublin Core), or, 2. Digital pathfinders (which may be built quickly through the reuse of resource records in the CORC Resource Record Database). 3. (Coming soon) authority records.

  32. Recent OCLC Project The differences among CORC, NetFirst and InterCat. InterCat was a project to encourage and investigate cataloging Web resources in WorldCat. Because the legacy OCLC Cataloging service was used, all records had to be acceptable OCLC MARC. A database of WorldCat records that have OCLC MARC 856 fields (currently about 92,000 records) is still being maintained and is publicly available, but the project itself is not active.

  33. Recent OCLC Project NetFirst is a database of Web resources available via the OCLC FirstSearch and OCLC Cataloging services. OCLC staff create what are basically abstracting and indexing (A&I) records, although they do include LC subject headings andDDC class numbers.

  34. Recent OCLC Project CORC is a leading edge, Web-based service that helps libraries provide well-guided access to Web resources using new, automated tools and library cooperation.

  35. Recent OCLC Project CORC is a natural extension of the InterCat and NetFirst efforts and takes advantage of newer technology to create an optimized metadata creation service. OCLC seeded the CORC database with records from the InterCat and NetFirst projects and encourage all InterCat participants to become CORC users.
