Although the Alzheimer's Association's Green-Field Library's catalog has be en available to local chapters and interested people for some time through modem access, placing the catalog on the World Wide Web would make it avail able to casual browsers as well as determined searchers. When a review: of the subject list revealed numerous inconsistencies and duplications, a neu: list was generated, giving preference to Medical Subject Headings (MeSH) w here possible. The result teas a mix of MeSH and Library of Congress Subjec t Headings (LCSH), augmented by a few local- and reviewer-supplied terms. T he neu: subject authority list gives the Green-Field Library an authoritati ve list of terms to use when performing original and copy cataloging It can also be placed with the library's catalog on the Web to aid users in perfo rming searches.
