In medicine what IM does not cover is primarily the non-English language less-important specialty journals. There is another indexing service that covers them well, Excerpta Medica.
It seems perfectly rational for both to exist: a University like ours, without a medical school, does not need Excerpta Medica but does need Index Medicus. A medical school library would want both. (Third-world journals were being covered a few years ago by a CD product called ExtraMed, does anyone know if this is a continuing project?) IM does indeed not cover non-journal material, and I suspect this is at present a gap in the bibliographic coverage of secondary services in many disciplines. Does CA cover individual chapters in monographs, for example? They can be articles to all intents and purposes. I don't think this is what Al meant, but I suspect that what we do need is more integrated indexing and cross linking, including not just formally published literature but preprints and so on. It is possible that new services like Pubsci, and other more sophisticated automated tools to be developed, may do better than the conventional services--and conceivably at a lower cost.
