articles are written by scholars in an academic or professional
field. An editor or editorial board reviews articles to decide whether they
should be published. These journals are called peer reviewed or
refereed journals. Journal articles may cover very specific topics
or narrow fields of research.
Since journals are published at periodic intervals,
they are grouped in the category of information resources called periodicals. They may be
in print format or on the Web as electronic journals. The library purchases subscriptions to many journals.
