 OLAC has published many reports, thought papers, and training materials over the years to support and advance the work of cataloging audiovisual materials.Currently, OLAC's work has focused on a series of 'best practices' guides for cataloging nonprint materials based on national and international standards.According to a 2007 study with 354 respondents, special format catalogers (i.e., non-print materials) report spending the majority of their time cataloging electronic resources, sound recordings (both audio and music), and video resources, and of these special formats catalogers 31% were members of OLAC.
