Hello there, Kovid: I just sent you an email, but in case it gets lost; I head up the editorial team at a small indie publishing house that's covered all its paperback novels with PDF versions for the past eight years (we have about 120 titles at www.bewrite.net
). If you think it would be of any help, please drop me a line and I'll send as many PDF ebooks as you might need to experiment with. Most are straight text, all well-formatted, some use more than one font and a few carry inside illustration. All are front covered.
Cheers and good luck. Neil
