PsycEXTRA® is a unique database that combines bibliographic records with full text professional and lay-audience literature such as legal testimony and amicus briefs, reports, conference materials, popular magazines, factsheets, grants, and web materials. It is a good resource for information and data for cutting-edge research and practice in the behavioral and social sciences and an archive of gray literature documenting psychology's development. The database contains publications such as technical and government reports, conference papers, newsletters, magazines, videos, press releases, and consumer brochures. There is a growing body of historical material in PsycEXTRA, including all issues of the APA Monitor to volume 1. The database also includes many important early works from the mid- to late 19th century, including vital conference presentations, that helped define and shape the study of psychology.
