My favorite book is a little known one called “Black Holes and Timewarps: Einstein’s Outrageous Legacy” and I reference it so much that I would really like a copy that’s fully mine and searchable, but I also care about the author receiving compensation for the purchase. Where do you get your PDF copies from?
If you can buy the ebooks in a different format (either DRM-free or with a compatible plugin), you can use Calibre to convert them to PDFs.
Who would you recommend for a good ebook provider with good author/publisher returns?
