Some high use periodicals are duplicated in microform. The Libraries maintain an approval plan for university press books as well as those published by outstanding trade publishers including Guilford and Lawrence Erlbaum. An effort is made to acquire nearly everything published by the American Psychological Association. The Libraries receive on subscription a substantial share of the English language journals indexed in Psychological Abstracts , as well as a selected group of foreign language titles. Gifts occasionally provide duplicate copies of heavily used titles but have not served as a major source of building collections in psychology.
Retrospective purchases are limited to filling in journal holdings or adding seminal older titles.
Upper-level textbooks are acquired selectively, as are works written on a popular level. Theses and dissertations from other universities are acquired only upon demand. Interest in various aspects of psychology, both clinical and theoretical, is widespread. The BF classification is one of the most intensively used in the libraries' collections, creating a need for multiple copies and replacement copies or rebinding of worn materials. Materials in education, management, statistics, sociology, and selected aspects of the medical literature including pediatrics, neurology, and works on nutrition are of interest to students and faculty in psychology.
