Go to the periodical's website:

• Are the Web graphics and content typical of a magazine?
• If there's a print version, does it look like a magazine?
• Does the publisher call it a magazine (see "About" and "Press Information")?
• Is there a cover price so that single issues can be sold?
• Does an annual subscription cost under $100?

What instructions are given to prospective writers?

• Are authors told to write for a general audience?
• Are manuscripts approved by editors (not peer reviewers)?
