The present volume represents the result of two years of work originally begun as a fifteen-member student project under my supervision at NASA - Ames Research Center, Moffett Field, Calif­ ornia. As a means of acquainting team members with previous research related to our NASA experiments with long-term isolation and confine­ ment effects upon nonhuman primate behavior a weekly meeting was arranged for students to orally present abstracts of various articles they had read. As the number of references increased we decided to expand our efforts through several computer searches of the psychological, biological, anthropological, and medical liter­ ature. Upon completion of our experiments at NASA, three of the team members and myself decided to take this basic foundation, up­ date, expand and otherwise polish it into the present comprehensive reference tool we feel confident will be of value to investigators and scholars interested in the broad topic of nonhuman primate development as affected by early environmental influences. While ours is the only bibliography of this literature which includes both abstracts and indexing, several previous publications are worth noting as we found them particularly helpful in our own work. Those bibliographies, compiled by Agar and Mitchell (1973), Stoffer and Stoffer (1976), and Roy (1976, 1977), are excellent. In addition to the articles cited in these sources we have added approximately 400 more articles with abstracts and indexing.
