My feeling has always been that self-POD thrives in addressing niche markets. These are small but significant markets not quite capable off producing the intense buying surge required to sell out an offset print run. These might be special interests, local authors, kinks and quirks, unfashionable genres or experimental works. But before I say anything more about this I have a question.
What sort of literature do you want to read, that the mainstream offset publishers are not providing, or not providing enough of?
