It would be best for you to get a bibliography from the Museum Reference Center at the Smithsonian for the basic core books on museology and museum studies. There is no ONE book (bible) for the museum field, but there are a number of good ones that will give you a solid background of information. Call or write to Valerie Wheat, Librarian...A&I Bldg. 2235, Smithsonian I., Wash. D.C. 20560. AAM and AASLH also have book listings.
