Science Fiction Writer's Marketplace and Sourcebook

Rating:
Summary: A good starting point, but not definitive
Review: This is a good place to start your search for places to sellyour work, but it is by no means the most exhaustiveresource out there. It lists the large and small publications that anyone interested in the genre should know about, but omits many more.

There are some useful tips in here as well, regarding subgenres and what editors look for, but once again this information is incomplete. Start with this book, then do some more digging on your own.
