Commercial Cataloging

One of the questions that comes up often on public and school library lists is: "Where can I find MARC records for AV?" I've just found a commercial source that may be useful for some institutions, marc4media. They provide MARC records tailored for the grade level being served.

Marc4media is a content-rich cataloging product designed to be the foundation tool for library media programs across North America. Our purpose is to align educational resources to learning tasks using language that encourages access by a wide range of teachers and students. Providing instant access to appropriate learning materials, marc4media is the key to integrating media into all aspects of curriculum development and student research.

I'm not endorsing these folks, just pointing to them as one place to explore.
