This document discusses problems and methods of language classification, especially with regard to questions of information storage and retrieval in connection with an information network for the language sciences such as that envisioned by the LINCS (Language Information Network and Clearinghouse System) Project at the Center for Applied Linguistics. An introductory section discusses the need for a comprehensive list of languages and stresses the necessity for at least some degree of grouping if such a list is to be useful and manageable. Section 2 presents some approaches to language classification, while Section 3 illustrates the following methods: alphabetic listing, genetic classification, areal classification, sociolinguistic classification, and typological classification. Section 4 then considers the features necessary for a language classification scheme which can be employed as part of an indexing tool in an information retrieval system, and the final section briefly discusses the Language Names Component of the proposed LINCS indexing tool. The appended annotated bibliography contains 32 entries. (FWB)
