1. What is PsycEXTRA?
PsycEXTRA is a bibliographic and full-text database of content from a variety
of highly regarded sources for "gray" literature in psychology,
behavioral sciences, and health. It provides key information for clinicians, researchers,
information professionals, policy makers, and consumers.

2. What is "gray" literature?
Gray literature is generally material for professional or lay audiences that is often
difficult to find because it is disseminated outside the traditional
peer-reviewed journal or scholarly book. Librarians have called this literature "ephemeral" or "fugitive" because it often appears only fleetingly. Materials include conference papers,
research reports, policy statements, standards, newsletters, magazines, newspapers,
brochures, fact sheets, annual reports and more. This literature is diverse, ranging
from brief consumer education materials to very substantive, rigorously researched,
and lengthy documents. Some are peer reviewed and some are not. The work of many researchers is found in gray literature
well in advance of any formal, peer-reviewed publication. Some researchers do
not submit their work to scholarly publications; consequently, the results of
their research can be found only in the gray literature.

3. Who produces PsycEXTRA?
PsycINFO, a division of the American Psychological Association (APA), produces
PsycEXTRA. PsycINFO is the most comprehensive
and authoritative publisher of bibliographic reference sources that cover scholarly
and peer-reviewed publications in psychology and related disciplines. The division
also produces the electronic versions of APA journals and books in the PsycARTICLES
and PsycBOOKS databases, as well as the PsycCRITIQUES database of book and film reviews.

4. How does PsycEXTRA differ from
the PsycINFO database?
PsycINFO includes bibliographic data and abstracts from scholarly, peer-reviewed
sources. PsycEXTRA does not contain data from scholarly, peer-reviewed journals,
so there is no overlap with PsycINFO. In addition to bibliographic data and
abstracts, PsycEXTRA also contains full-text content for a large percentage
of documents covered.

6. How much retrospective
coverage does PsycEXTRA have?
Many of the document types covered in PsycEXTRA such as conference papers, technical
reports, brochures, and facts sheets are one-time publications. No retrospective
coverage can be provided for these, although original documents are retained
in the database along with any updated or revised editions. 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 studies.
