A journal's publication date usually consists of the volume, number and month/year. Each volume of a journal series comprises a certain number of issues; the journal may publish two (semiannually), four (quarterly), six (bimonthly), or 12 (monthly) issues per year. Therefore, the volume number tells you how many years the journal has been published, and the number tells you which issue this is of the volume year. The month/year information indicates the month or month range (e.g., April -- June 2010) during which that number of any given volume is published. You can spot this information in various places on the journal.
Look at the front cover to locate the volume, number, and month/year. It is often in a corner, near the top or bottom of the cover. Example: Volume 41/Number 2/April - June 2010.
Turn the journal to its side to view the spine (the strip that binds together the front and back covers). The information is often at the far right or left side of the spine. Example: Volume 102/Number 6/November - December 2011.
Open the journal to the Table of Contents, usually located on the first or second page. Find the journal's publication date above or below the Table of Contents. Example: February 2010/Volume 89/Number 2.
Search the back cover of the journal if you are unable to locate the publication date in the locations described above. In a few cases, the publisher might print the Table of Contents on the back cover.
If the journal does not clearly state which is the "volume" and which is the "number," it is likely that the larger number is the volume and the smaller one is the number. The information is also sometimes printed like this: 41 (2)/April -- June 2010. In this case, the volume is located outside the parentheses and the number is found inside the parentheses.
If you are viewing the journal online, you will be able to find the journal's publication date by clicking on "Current Issue." Example: October 2010; 45(4).
