Books
These books are a great place to get acquainted with the world of writing and publishing. Be careful of using a market guide that is more than a year old--the people and contact information may have changed or the magazine or publisher may be out of business. If you do use an older edition, make sure you call or write first to check the status of the publisher or magazine and whether they are still accepting submissions.
