I don’t bring it up often, but one of the publications I edit is The SFWA Bulletin. We publish non-fiction at 10 cents/word and both members and non-members are welcome to submit. You can find the guidelines here.
From time-to-time, people make suggestions for the types of articles they would like to see us publish. Currently, this list includes the following topics:
Book Trailers (pros, cons, how-to, why)
Selling Books at Conventions (getting my own table vs teaming up vs commission)
Understanding Print on Demand and it’s relationship with bookstores (who carries what and why)
Essential Elements of Author Websites (We’ve done this before, but trends change)
Audiobooks (what’s the marketplace like, should I get in, how?)
If any of these are within your area of expertise, please consider pitching an article.
Also, I’m looking for people to help cover the Nebula Awards Conference, so if you will be attending this year and have an interest, please contact me at the address listed in the guidelines.
