There’s always Google (my favorite Internet word) but it’s more productive to browse through a list.
For those of you ready to query (or you will be very soon) here’s some sites that will help you find your dream publisher:
Publishers Global - I recently discovered this site and it’s a gold mine! A very large listing of publishers from around the world. It also lists publishing resources much like the Literary Marketplace - printers, distributors, illustrators, etc. Excellent site!
Publishing Central also has a list of publishers and you can search by genre. (Be warned - the first couple presses listed in any search are often subsidy presses.)
Every Writer’s Resource has a listing of publishers - and more.
Everyone knows Preditors and Editors! You can only search by name, but it great for checking out potentially bogus publishers, editors, and agents.
SFWA has a section called Writer’s Beware.
And Aeonix explains why you should avoid subsidy presses.
Before you begin searching for the ideal publisher, be sure to visit BISG and determine your manuscript’s exact genre.
