This preliminary bibliography was prepared as a listing of background materials for use in connection with the development of an experimental thesaurus for the language sciences. The first half of the bibliography contains references to 68 sources of information on indexing materials in the language sciences. Actual indexes, lists of specialized terminology (thesauri, dictionaries), and other classification systems are arranged by author. Part II of the report consists of 74 entries, mainly dictionaries, which deal with the terminology used in the field as a whole as well as sources which are concerned with terms used in a single language or language family. A few articles on terminology have been included because they contain highly relevant information or further bibliography citations. Brief annotations provide background information for some of the entries. (Author/JD)
