INSTRUCTIONS

To take best advantage of these books, place the ABEBOOK folder at
  the root of whichever drive is hosting the library.

This will allow the Style Sheet (ABEBOOK.CSS) to uniformly enhance
  the viewing of all compatible books. The abebook.css file can be
  modified to customize the appearance of compatible to your own
  personal preferences.

The "background.jpg" file in that folder can be deleted or changed
  to suit your preference as well.

If you have any questions, post them to alt.binaries.e-book,
  attention "Wallaby".

Enjoy!
