A while back I posted a note about Hard Case Crime (
http://www.hardcasecrime.com/). I contacted the publisher as only one of their books (the Stephen King one) is available electronically.
The publisher said they didn't have the demand yet to do electronic versions, but were 'open' to comments from potential customers.
Nice selection of pulp/noir/hardboiled detective fiction. I've read several in paper. Some are reprints, some are current, all have 50ish type covers.
So, if the publisher gets more e-mail...
