A Growing Collection of High-Quality Content
PsycEXTRA contains more than 294,000 records that are not indexed in any other APA database, and content from the Archives of the History of American Psychology (AHAP) collection is expected to increase the number of records substantially.
In addition, PsycEXTRA is indexed with controlled vocabulary from APA's Thesaurus of Psychological Index Terms®.
My overall impression of the EBSCOhost interface is that it offers something for everybody.– Charleston Advisor
