Thanks, that's interesting too. One of the most useful lists I've found is actually in ONIX, Code List 7. http://www.editeur.org/codelists.html Although Code List 7 actually needs to be supplemented by Code List 78 if you want full detail. (Like whether a VHS tape is NTSC or PAL; or the fact that a printed book is in Braille (US or UK? Can specify either, hooray.)). The ONIX list is a pretty good and complete list of physical formats for published items, and appears to be free, and is available in XML as well. It does become an awfully LONG list. And is still not entirely intellectually consistent---the article Diane pointed to in D-Lib is the result of trying to harmonize this with library practices in an intellectually consistent way, but it becomes something so abstract that it's kind of hard to deal with, and also leaves many vocabularies unspecified. I think a more or less flat list with specified vocabulary, even if not entirely intellectually consistent, that corresponds to the universe of actually existing published items, is probably more useful.
