This collection development policy provides a framework within which library faculty subject specialists at Western Washington University make library material acquisition decisions. The collection policies address aspects of collection scope and collection intensity, current needs and long-term goals of the university's academic program and stated curriculum. Individual policy statements describe and define the library's intentions in building its major subject collections, each of which serves the needs of a number of university programs. The statements are arranged in alphabetical order and include: agriculture; anthropology; art; biology; business, commerce, and accounting; chemistry; children's literature; economics; education; educational curriculum; English and American language and literatures; finance; foreign languages and literatures; geography/regional planning; geology; health sciences including nursing and speech pathology/audiology; history; literature (general); mathematics and computer science; music; philology, linguistics; philosophy; physical education, recreation and dance; physics, astronomy; political science; psychology; religion; science (general); sociology; and technology. Archives and government documents, two major non-subject units, are also covered. Each statement notes the library faculty member responsible for that collection and defines the collection in terms of its general purpose and how it relates to the university's instructional program. Information on general policy regarding nonprint materials is found in a section covering Technical Policies. A conspectus describes the collections in terms of the 500 major Library of Congress subject area classes. The document includes an index. (THC)
