-- Participating libraries will identify, select, and catalog Internet accessible electronic information objects.
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.
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.
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.
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.

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).
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.
Fifteen core descriptive elements were chosen. These core elements were referred to as the Dublin Core:
6. Other contributor
8. Resource Type
10. Resource Identifier
15. Rights Management
Metadata workshops and related events have taken place all over the world each year.

CORC--Cooperative Online Resource Catalog
CORC is a research project exploring the
cooperative creation and sharing of metadata
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.
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.
CORC offers four searchable databases:
CORC Resource Record Database
CORC Authority Database
CORC Pathfinder Database
Dewey Decimal Classification Database
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.
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).
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.
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.
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.
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.
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.
