Besides using briefs for getting some free publicity, and having your name, or company printed in a magazine, newspaper, etc. you can use briefs elsewhere.
Other Uses for Your Briefs
 Make reprints and tuck them into your media kit.
 Make reprints and use them in your handouts if you do public speaking.
 Post them at your web site.
 Include them with a pitch letter to editors at other publications if you're trying to get a larger article placed. This shows that you have been published and establishes credibility.

Here's an example of a brief submitted to a small-business magazine:

Joan Stewart
Simultaneous Submission, Non-Competing Market
3930 Highway O S.S. # 123-45-6789
Saukville, WI 53080 298 words
262-284-7451
