Ulrich's (Library Home Page > Databases > U > Ulrichs OR Search Ulrichs in the Search box) or the publisher's web site are two major places to learn more about a specific journal, such as:
This database provides bibliographic information for newspapers, magazines, and journals published in the United States and internationally. It also distinguishes peer-reviewed journals (or "refereed") from popular magazines.
In Ulrich's search for a journal title and select the correct journal. (You may see multiple versions with the same title if both online and print versions exist, or if the journal has changed publishers. TIP: If you get too many results, search Google for the ISSN (International Standard Serial Number) of the journal. This is unique to the journal and you'll get better results.)
Click on the journal title to check the description and make sure it is the correct publication and find more information about the journal.
The publisher website for a particular journal has information about editorial and submission policies. You can search Google for the journal title; the Ulrich's profile for a journal also provides the publisher's website.
Submission information and editorial policies for a journal are usually not on the homepage. Look for About, Contact, Instructions to Authors, Author Guidelines, or Contribute links.
