Two more minor additions, if you've bothered to scroll down this far.
Victor Gischler, whose Adams Media-published The Deputy was a freebie late last year, offers a collection of his previously unpublished early paranormal PI stories:
Three On A Light.
Leslie Wooddavis offers a hard sf novel which seems to have been paperbacked sometime in 1999:
Rune Logic. She does have some other book paper/Kindle-published by some "publisher" which carries other authors, so probably not entirely glorified vanity self-pub.
