My publisher is pushing me to write for kindle type readers, because it costs them less than the traditional binding and distribution methods. I write limited edition mysteries and the field is very competitive. Although, I am not going to tout my books here, I do want to say, that my publisher has gone away from hard covered books, because the cost of printing is getting more expensive with every printing, plus with soft covered pulp fiction books, they can pay less to authors, because there is a lot of writers out there.
I understand a huge appeal of limited edition press copies is that they are 'limited edition', sometimes slip-cased/limited runs and such, and that much of the appeal lay in that aesthetic of their design/make-up/scarcity. Surely by going digital aren't you removing much of that appeal?
I know of several small horror publishers going digital for similar reasons of cost, but there's also the fact that they were only able to become perceived as traditional publishers due to the fact they producted hard-copy books despite these having small print runs/low costs etc.
I wonder whether such books will see comparative sales of digital copies vs. traditional print media. I also wonder whether we're ultimately just going to see lots of smaller publishing houses appear who are knocking out copies by certain authors who wouldn't have been published otherwise, eventually leading to people turning more to the traditional publishing houses for assurances of quality etc.
