This bibliography is based on the author's thinking and experience with implementing the unified education concepts through the team-taught Unified Studies Program at Boston State College, 1972-75. The purposes of the bibliography are to test a new approach to user-oriented bibliographical notes, provide information about how to find information concerning interdisciplinarity, and reshape the use of certain words (interdisciplinary, crossdisciplinary, multidisciplinary, transdisciplinary, and unidisciplinary). A user-oriented compendium, the bibliography is laid out developmentally--(1) getting ready to think about interdisciplinarity, (2) thinking about interdisciplinarity, and (3) implementing interdisciplinarity. It is personal, historical, and selective and focuses on theoretical and practical obstacles to interdisciplinarity. Several sources are included in each of the three sections and are briefly discussed in relation to the obstacles. (Author/ND)
