This bibliography of recent dissertations (1970 to March 1975) on the subject of attrition and retention of college students is intended to serve as a resource guide for administrators and for research in higher education. The arrangement is by type of institution for which the data were collected (public community colleges, public colleges and universities, private colleges and universities, and others), subdivided by studies of a single institution and by those studies that included data from two or more institutions.
