Moving Image Genre/Form Project Report

In early 2007 the Cataloging Policy and Support Office (CPSO) of the Library of Congress initiated a project to create authority records for genre/form headings (MARC tag 155), which indicate what a work is, as opposed to what it is about....

This past Tuesday members of CPSO presented a report on the moving image genre/form project to LC managers. The report

• explains the function of genre/form headings, including the impact that they have on both cataloging operations and end-user searching;
• reviews the history of genre/form headings in MARC format and at LC over the last decade;
• explains the logic of choosing moving image headings as the experimental group and the principles and policies that CPSO developed as the project progressed; and,
• recommends the expansion of genre/form headings beyond moving images and radio programs into such disciplines as law, music, literature, cartography, and religion.

From an email message.

The report says that the prefered method of entering genre/form information is 655 rather than subfield v. Is this the general consensus? Has any research been done? Any MLIS student even written a paper on the pros and cons of each approach?
