In early 2007 the Library of Congress began a project to create
genre/form headings, which describe what a work is rather than what it
is about. To date, over 500 headings for moving images (films,
television programs, and video recordings) and sound recordings have
been approved.
Two years later, in 2009, the Policy and Standards (PSD) and Geography
and Maps divisions of the Library of Congress began work on the next
genre/form project to go into production: cartographic materials. PSD
will be approving new cartographic genre/form headings (MARC 21 tag 155)
and revised form subdivisions ($v) in stages over the late spring and
summer of 2010, and plans to implement the new system no earlier than
August 1, 2010. Be advised that LC will not implement any aspect of the
cartographic genre/form headings until all of the elements are in place.

A tentative timeline for the approval of the cartographic genre/form
headings, the revisions to the form subdivisions, and LC’s subsequent
implementation of them is available on PSD’s web site at   

Additional information on the genre/form projects at the Library of
Congress can be found on PSD’s genre/form web page,  The page
includes a timeline, an extensive FAQ, reports, discussion papers, and
announcements.  Questions and comments on the projects may be addressed
