Several librarians at my institution were interested in seeing/listening to the MeSH at 50 – 50th Anniversary of Medical Subject Headings by Robert Braude at NLM a few weeks ago. Unfortunately at the time, we couldn’t get it to work correctly for some reason.
Good news, the program is now available under Past Events on the NIH’s videocast site. One of the librarians here has already viewed it and said that much of the talk is about “what was (and wasn’t) available/used BEFORE MeSH, and about the initial development of MeSH itself.” The program lasts about an hour and according the one viewer, there aren’t a lot of “visuals” so it is easy to listen to while multi-tasking at your desk.
