Journals and journal articles
Journals are publications that specialise in a particular subject area, containing a series of short, in-depth articles which describe or report on new research. Journal articles go into detail on very specific subject areas, and recent journal articles are a primary source of the latest research.
Journals are produced on a continuing basis and can also be known as periodicals or serials. Some journals produce a new issue each week or month but others are quarterly or annual. Issues of a journal are often grouped and then referred to as a volume. As journals are published more quickly and more often than books, they can give more up-to-date information.
If a journal is peer-reviewed it means experts check the content before it is published. Not all journals are peer-reviewed; check the journal's website to find out if it is.
