This bibliography is the sixteenth supplement to the original work, which covered 1934–1969. The supplements include all titles of earlier years that were found after the original bibliography was published in the journal of Gerontology, 1971, 26,391–422. Due to the nature of bibliographic control in regard to doctoral dissertations, each supplement will try to cover the academic year rather than the calendar year. This means that a dissertation issued in 1970 may be either in the original bibliography or in the supplements. Both on-line and manual search techniques were used in the compilation of this supplement. The arrangement of the supplement is similar to the original bibliography. [ABSTRACT FROM PUBLISHER] |
