Is there any indexing tool,accessible by subject, which is limited to consumer health audiovisuals? I've been on Locator, AV Line and Melvyl, but the pickings are slim for popular works. Evaluative reviews would be especially useful. The present subjects of interest are diabetes mellitus (any type), asthma, and carpal tunnel syndrome or repetition strain injury. Any leads? -The main format desired is video. Thanks in advance for any help!
