I’ve written about VDM (Verlag Dr. Mueller), an exploitive academic/scholarly mill before.
Writer Beware writer advocate and writer Victoria Strauss notes that VDM has a new wrinkle:
. . . a company called Bloggingbooks that wants to publish your blog in book form
Run away; you can do this yourself, if you really want to, via any number of online service companies. You won’t make much money, but you are less likely to be exploited.
