Writer's Resource: Writer's Market

Looking for writer's guidelines for just about any publication on the market? Check out Writer's Market. You can pick up a copy of Writer's Market which is updated yearly and costs about $30. There is also an online version that requires a subscription (which you may cancel at any time.) I prefer the book edition -- I find it more comprehensive. But for travel writers it isn't very practical to lug around that huge book! The online version allows you to access the database from any computer, all over the world!
