Several previous posts came from Snarklings hearing things on writers boards, or from the ether, or other sources. A comment asks:
In all seriousness, how do people get this sort of info? How can the great unwashed, er, I mean unpublished keep up with current events?
My advice: don't. Most of the posts on this topic have been people getting information that is either suspect or wrong. Writer's boards can be useful. They can also fuel your anxiety. They can be the home of people who think every agent is out to pick your pocket and the publishing industry is second only to Congress as a den of thieves. A question of "what do you know about Miss Snark" that elicits "she spends too much time on her blog to be a real agent" is not only snotty, and wrong, it's not the answer you're looking for.
If you really want to be plugged in and read what agents are reading, subscribe to Publishers Marketplace and Publishers Weekly. It gives the basics of who is buying what, who's selling what, and factual information. Miss Snark posts her sales to Publishers Marketplace regularly and you'd know she is both 1. real; and 2. making sales even as she blogs.
Your job is to write well. Every minute you spend worrying, or wondering about rumors is one minute less doing something constructive.
If you have spare time on your hands, read more great books. And this blog of course too.
