PsycEXTRA®, produced by the American Psychological Association (APA), is a bibliographic and full-text companion to the scholarly PsycINFO® database. The document types included in PsycEXTRA consist of technical, annual and government reports, conference papers, newsletters, magazines, newspapers, consumer brochures and more.

This database complements PsycINFO and the other APA databases with extensive coverage of gray literature relating to psychology and the behavioral sciences; it contains nearly 170,000 records that are not indexed in any other APA database. Furthermore, content from the AHAP collection is expected to increase the number of records substantially. PsycEXTRA is indexed with controlled vocabulary from APA's Thesaurus of Psychological Index Terms®.
