OCLC Web Sessions and Recorded Presentations

There was some talk on AUTOCAT recently about LC genre and form headings. Though I tend to head to the Online Audiovisual Catalogers online site, I just learned that OCLC has a web session that you can play or download for free on LC genre/form headings. Even if you missed the originally streaming version (May 3 or 12, 2011), this is a handy reference. The web session is an hour. The presentation, by Linda Gabel, introduces genre/form headings in terms of definitions, sources, or how to search for genre/form headings. This material is introductory. If you are already familiar with genre/form headings, I would skip this presentation.

Library of Congress Genre/Form Terms Leave LCSH

Well we were waiting for this moment when the genre and form terms would be separated from LC subject headings. That date is now set on May 24, 2011.

Here’s the blurb from LC:

[This message has been widely cross-posted.  Please excuse any duplication.]

Since 2007 the Library of Congress’ Policy and Standards Division (PSD) has been developing genre/form terms, and in June 2010 determined that the new thesaurus, Library of Congress Genre/Form Terms for Library and Archival Materials (LCGFT), should be formally separated from Library of Congress Subject Headings (LCSH).  In order to accomplish this, on May 24, 2011 the existing genre/form authority records will be deleted and reissued with new coding.

The current coding for the genre/form authority records indicates that the terms are from LCSH, not LCGFT.  The LCCNs are prefixed by “sh” and 008/11 is set to “a,” Library of Congress Subject Headings.  Therefore, the LCCNs and MARC coding both need to be revised.  This will require the deleting and reissuing of the genre/form authority records.

The approximately 800 existing authority records will be deleted and immediately reissued.  About 1600 records (deletes plus reissues) will be sent to subscribers as part of the May 24, 2011, Volume 26, Issue 21, distribution of subject authorities via the MARC Distribution Service (MDS).

Authority records for LCGFT terms will be coded as follows.

LCCN prefix:  gf

008/11: z (“Other”)
040$f: lcgft


008/11             z

010                  $a gf2011987654 $z sh2009025020

040                  $a DLC $b eng $c DLC $f lcgft

155                  $a Topographic maps

455                  $a Hypsographic maps

455                  $a Hypsometric maps

455                  $a Relief maps

455                  $a Topographical maps

555                  $w a $a Maps

[Note that the deprecated LCCN is being retained in field 010$z, to facilitate automatic updates.]


As of May 24, 2011, new coding should be used when assigning LCGFT terms in bibliographic records.  That coding is as follows.

655 #7 $a [Term]. $2 lcgft


            Title:  Survivor: Thailand.

655 #7 $a Survival television programs. $2 lcgft

655 #7 $a Nonfiction television programs. $2 lcgft

The genre/form FAQ http://www.loc.gov/catdir/cpso/genre_form_faq.pdf and the Subject Headings Manual (SHM) will both be updated to reflect this change in policy.

For further information and the rationale for these revisions, please see the January 3, 2011 announcement, “Library of Congress to Reissue Genre/Form Authority Records.”  http://www.loc.gov/catdir/cpso/gf_lccn.html

Questions or comments on these plans or on the genre/form projects in general may be addressed to Janis L. Young jayo@loc.gov, LC’s genre/form coordinator.
