A bibliography of doctoral dissertations on aging from American institutions of higher learning, 1975-1977.

This bibliography is the seventh supplement to the original title which covered 1934-1969. The supplements include all titles of earlier years which were found after the original bibliography was published, Journal of Gerontology, 1971, 26, 391-422. Included in this year's supplement are 15 titles identified in a search of the Datrix data base which covered the years 1856-1934. Due to the nature of bibliographic control in regard to doctoral dissertation, each supplement will try to cover the academic year rather than the physical year. This means that a dissertation issued in 1970 may be either in the original bibliography or in the supplements. The arrangement of the supplement is similar to the original bibliography.
