Robert Brewer, editor of Writer's Market and Poet's Market, is looking for articles for the 2013 editions of both books. He's seeking business-related articles about the writing life, and queries should be in by August 8th. (Read the full guidelines on Mr. Brewer's blog.)
In addition to articles, he's also looking for poems to be considered for the 2013 Poet's Market. This could be a great opportunity for any poet. Only 20 poems will be accepted, and the chosen ones will receive $50 and a copy of the book. The deadline for poems is August 15th, and those guidelines can also be found on the editor's blog.
