The 2004 edition of Writer's Market is as complete and wonderful as it is every year. The massive paperback is brimming with tips and information about the craft as well as the business of writing. It is complete with contact information for book publishers, agents, and magazines. It also has a section on contests and awards, and a nice glossary. It is a good value.My one gripe is that the book has ads in it. I count three cardboard inserts advertising their magazine, their Web site, workshops, and their other books.
