Auburn Procedures for the CORC Project

CORC stands for Cooperative Online Resource Catalog. It is a joint project between OCLC and participating libraries to create and share metadata of World Wide Web sites. The CORC database presently supports Dublin Core and MARC formats.


Policies for Creating CORC and Related Voyager Records

Auburn will begin by concentrating on web site links listed on the various departmental home pages. These links have already been selected by reference librarians. Glenn Anderson and the subject bibliographers will recommend other links. Catalogers should exercise judgement on whether to add records for links present on the above web sites or to add records they feel of value. Catalogers should focus on web sites of actual bibliographic entities. There are three basic types of web sites which should be cataloged in the CORC database:

  • associations
  • e-journals and databases
  • electronic monographs
  • lists of links to other web sites

If a web site contains indexing to a journal, but does not include the journal, do not create a CORC record. If the journal is already in Voyager, add a link to the journal record. When choosing between two or more CORC records, use the record that best fits the site or the one that is the fullest. Prefer records that are not created by N@F because these were tapeloads.

Export records for associations already in CORC straight to Voyager. Associations should receive minimal editing because they are not really bibliographic data and will hopefully become part of the proper authority records in the future.

For e-journals and databases, add a record to CORC if one does not already exist. Before downloading these CORC records to Voyager, check OCLC for an existing MARC record of the e-journal or database. Prefer OCLC records over CORC records for export to Voyager. Upload records we create in CORC for e-journals or databases into OCLC via CatME if they are not already in OCLC. Do not load other libraries' CORC records into OCLC. All websites should be treated like loose-leaf and receive a minimalist approach.

Treat a web site with a list of links to other web sites as a bibliography. For cataloging purposes, treat bibliographies of links with the level of cataloging given to e-journals and databases.


Cataloging of CORC Records

When creating records in CORC, choice of format is left to the cataloger. Be aware of differences between the formats. The computer file MARC format (Type of record "m") is now used only for computer applications (see definition below). Websites and remote e-journals are no longer considered to be computer files. They receive an "a" in the type of record field instead of an "m" and they do not have an 007 field. Locally, we will change web sites to type of record "a", ignore the 007 field, delete the 006 field, and use the general material designation (gmd) "electronic resource." However, we must still use the gmd "computer file" in CORC until national policy catches up with us. For retrospective conversion purposes, we will follow this procedure from now on and correct other records as we find them. Jack's unit will systematically change older records in the AU database, but not in the GP database. Government documents will not be changed since they frequently get overlaid.

Type of record = m (computer file)
Code m indicates that the content of the record is for the following classes of electronic resources: computer software (including programs, games, fonts), numeric data, computer-oriented multimedia, online systems or services. For these classes of materials, if there is a significant aspect that causes it to fall into another Leader/06 category, code for that significant aspect (e.g., vector data that is cartographic is not coded as numeric but as cartographic). Other classes of electronic resources are coded for their most significant aspect (e.g. language material, graphic, cartographic material, sound, music, moving image). In case of doubt or if the most significant aspect cannot be determined, consider the item a computer file. (From the USMARC Format for Bibliographic Data, Leader/06 category)

Each CORC record should have the title, author(s), subject headings, and an LC class number without a cutter. Add a 516 field which should read "516 $a World Wide Web resource." Do not add a 538 field (it repeats the information in the 516 field). The 653 fields for key words are optional. Ignore the 270 field, but delete the 256, 538, 092, and 699 fields (the latter two are Dewey call numbers).

Take the title from the web page, not the html source title. Record the latter in a 246 field: "246 1 b $i HTML source title: $a [title]." Always provide a 500 field with the following text: "Viewed on [date]; title from web page." Include this note on all original cataloging. If the title is taken from a source other than the web page, the note should give that location.

Dates for web sites should be treated like dates on loose-leaf materials. In the 008 fixed fields, the Publication Status should be "m" for multiple dates. Date 1 should be the date on the web site. If there is no date on the web site, put "199u" in Date 1. Date 2 should always be "9999". The date in the 260 should be left open. Dates for e-journals should follow the rules for print journals. Dates for electronic monographs should follow the rules for print monographs.

Place a brief description of the web site or e-journal in a 520 field. Eventually links to electronic resources will be automatically generated from the catalog to a reference page. The Reference Department would like to have descriptions automatically generated at the same time and the 520 is the most appropriate field.

For all electronic resource records in Voyager, add a 710 02 field for the following codes: in the $a, use QER (electronic resoure), QEJ (electronic journal), or QEM (electronic monograph) and add an F if the site is free. Then, in the $b, add CORC, with the addition of an A if it is an association or some other type of authority information. Ex. "710 02 $a QERF $b CORC." This information should also go on the holdings record in an 583 field. Ex. "583 $f QERF $j CORC."

Once the record is in Voyager, move the 856 field to the holdings record. If access restrictions apply, put a "506 b b $a Access restrictions may apply." on the bibliographic record AND the holdings record. Leaving the 506 field on the bibliographic record is helpful for reference librarians and patrons.

When the record is finished in Voyager, add a 948 field on the bibliographic record: "948 $a cat, date (mmddyyyy), [initials]". Alternatively, on the holdings record, add a $a in the 583 field and retain the $f and $j. Ex. "583 $a [initials], date (mmddyyyy) $f QERF $j CORC".

When doing statistics for CORC records, consider work in CORC and records added to Voyager as two separate types of records for the same data. So count each CORC record edited or created as one CORC record on the statistic sheet. If the record was done by another library and it or an equivalent OCLC member record is exported to Voyager, count that as an electronic resources member copy. If the CORC record is created by Auburn and uploaded to OCLC, then exported to Voyager, count that as an electronic resources workform. If the CORC record is created by Auburn and exported directly from CORC to Voyager (in the case of associations), that also counts as an electronic resources workform.
