Guide to the Fields in PsycEXTRA® Records

APA Databases records are divided into fields, which makes searching the databases easier. What goes into each field varies depending on the type of literature we're documenting.

This guide lists all the fields, plus an explanation of what each field does. The * indicates a field that is display only (not searchable).

We also have a printer-friendly version of this field guide (PDF, 60KB).
