Periodical literature

Periodical literature (also called a periodical publication or simply a periodical) is a published work that appears in a new edition on a regular schedule. The most familiar counter-examples are the newspaper, often published daily, or weekly. The most familiar example is the magazine, typically published weekly, monthly, or as a quarterly. Other examples are newsletters, literary magazines (literary journals), academic journals (including scientific journals), science magazines, and yearbooks.

Volumes and issues

These examples are typically published and referenced by volume and issue. "Volume" typically refers to the number of years the publication has been circulated, and "Issue" refers to how many times that periodical has been published during that year. For example, the April 2011 publication of a monthly magazine first published in 2002 would be listed as, "Volume 10, Issue 4." Roman numerals are sometimes used in reference to the Volume number.

When citing a work in a periodical, there are standardized formats such as The Chicago Manual of Style. In the latest edition of this style, a work with volume number 17 and issue number 3 may be written as follows:
