MASC(Manuscripts, Archives, and Special Collections) is a legacy database of the Manuscripts Division of the Department of Rare Books and Special Collections of Princeton University Library. Consisting of almost 100,000 records, it provides non-book holdings information for more than 23,000 individuals (and corporate bodies) in more than 1200 collections distributed among the various units of the Department. These include the Manuscripts Division, the Theatre Collection, the divisions of Western Americana, Graphic Arts, Maps, and and Numismatics. But it has not been maintained for a number of years, and, as a result, some of the records have been revised, replaced, or deleted.
There is a collection-level record for many of the collections in the Manuscripts Division of the Department, which supplies its main entry, range of dates, scope and contents, arrangement, and various subject and form access terms.
Most of the records, however, are indexing records that locate specific "author" material within those collections: for example, letters by Ernest Hemingway in box 49 of the F. Scott Fitzgerald Papers. In addition, author records contain brief identification and biographical information about the indexed "authors," or creators, of the material being described.
The most current information about specific manuscript collections in the Department is available in the Princeton online catalog(http://library.princeton.edu/) and in the EAD finding aids site (http://diglib.princeton.edu/ead/ )
