Well, we can already see the effects on availability at smaller retailers.
For the past couple of weeks, a large chunk of Fictionwise's
new offerings in the secure column were authors I recognized as being from Random House imprints. They had stuff by Anne McCaffrey, Barbara Hambly, Barry Hughart, etc., and the list was generally much longer than the MultiFormat offerings in the left-hand column.
This week, there's a lonely single Harlequin sitting in the Secure new releases column and all the above authors have disappeared entirely from the catalogue.
Kind of scorched earth, really.
