This document consists of the four issues of a serialized annotated bibliography on the teaching of modern languages published during 1990. The bibliographies are published quarterly by a German information dissemination system similar to ERIC and list items compiled in conjunction with the ERIC Clearinghouse on Languages and Linguistics and a number of other similar institutions around the world. Entries include mostly German, French, English, and Russian titles. The bibliographies are made up of three main sections, Including: (1) an alphabetical author/title listing with bibliographic citations and subject index terms; (2) abstracts in German; and (3) a subject index developed from the descriptor terms assigned to each entry. Lists of sources (periodicals, publishers, and institutions) are cited, and a cross-reference index is included. (VWL)
