Does it support the Kindle or Nook apps? They're free. If you have those, you can get gobs of free books on the Kindle free store (and, I assume, something similar for Nook) or from Project Gutenberg. Many of the books on PG are also available in .pdf format, so if the tablet has a .pdf reader, you're good to go, there.
As to transferring from PC, you'd still have to have the appropriate reader on the tablet.
