A 1970s Broadman Press Media Cataloging Book

An essential part of Church or Christian Librarianship is cataloging. A recent find in my research on Christian media is this copy of "How to Classify and Catalog Media: Technical Processes 2" (1978) from Broadman Press by Jacqueline Anderson

This resource gives a 1970s window into the complex world of organizing analog  film and audio formats on all topics. I am hoping that this old guide can help me learn more vintage Christian audio visuals.
