Another popular writing magazine, Writer’s Digest is a shorter publication with an emphasis on improving writing and getting published. It features articles related to grammar, style, and making your writing accessible (for example). At the same time, it has down-and-dirty details like how to break into the business, get an agent, demand payment, and use editing options (generally written by authors, agents, and editors). They do mention contests and conferences, as well, though not as comprehensively as Poets & Writers.
This one is geared more exclusively toward aspiring authors rather than published ones. Its smaller size makes it a bit less comprehensive, but that doesn’t make the information any less useful. If you’re looking to get published, this one is a quick, handy resource.
