The material development needs for the Southeast Asian languages are analyzed as follows: (1) both student and reference grammars must be produced; (2) student and reference English-Foreign Language dictionaries are needed; (3) research is needed in sociolinguistics, semantic analyses, linguistic surveys; (4) elementary, intermediate and advanced teaching materials are lacking in primary and secondary languages; and (5) teaching facilities and centers for the study of these languages are lacking. A report from the conference held in 1959 at the American Council of Learned Societies is also furnished here, with its determination of needs and recommendations for research. Requirements included basic language courses, graded readers, reference grammars, orthographic systems, student dictionaries, instructional tapes, area handbooks and other resources. General recommendations for programs to develop neglected languages were outlined, and specific needs for Burmese languages, Thai, Lao, Cambodian, Vietnamese, Indonesian languages and Tagalog were detailed.
