This two-volume monograph on bilingualism, a "major, virtually untapped national resource," is based on three extensive field trips to current bilingual programs: (1) in the Northwest as far north as Barrow, Alaska; (2) the Southwest and Hawaii; and (3) from Dade County, Florida, north through Washington, New York, New England, and into Canada. In addition, almost all the bilingual programs in Texas were visited. This study presents a history of bilingual schooling, both in the United States and in other parts of the world; alternative concepts of bilingual schooling; sample curriculum models; implications for education and society; and an outline of needs, as related to action and research. Volume I includes an 870-page annotated bilbiography with index, and an index of terms. Volume II contains appended data on the Bilingual Education Act; draft guidelines to the Bilingual Education Program; demographic data; notes on immigration legislation; a typology of bilingual education; socio-historical notes on bilingualism in the United States; descriptions of non-English speaking ethnic groups in the United States; a directory of persons, organizations, and sources of teaching materials; names and addresses of USOE Bilingual Design Project Advisory Committee members; and a list of invited guests at the Conference on Bilingual Schooling in Northlake, Ill.
