The only writers listed with BKNelson I never heard of; the books listed are apparently available only through Nelson, not Amazon or other venues. There is nothing on forthcoming titles, they're stingy with practical information, and what's with that guest speaker stuff?
On my agent's site there is an extensive list of dozens and
dozens of writers I
have heard of (and read!), links to their websites, and lists under each name of books sold through the agency.
On my former agent's website: another long list of clients and books sold, click on a name, go to a website.
On the website of an agent I've heard mentioned most of my professional life: a lengthy list of recent and forthcoming books, plus a notice that they will only look at MS from writers who have sold to
bona fide publishers. (Guess that leaves out Publish America.
)
So...there's three legit agencies with certain points in common: lists of writers, links to websites, books out, books to come, and submissions guidelines. I found all the details in less than 5 minutes worth of googling, and not one trace of rocket science know-how was needed.
And then there is the "mystery agency." I'm thinking the only way to get more info from it is to become skilled in the ol' Vulcan mind meld...only I don't wanna get that close to anything that smells THAT fishy!
