Just a quick remark here :
with at least some torrent downloading programs (Azureus, for instance), you can choose which files to download, so you're not forced to get all the files if you need only one.
The GUI for this may not be very easy to use and you might have a bit of trouble finding the exact book you need between the thousands in the archive, but the possibility exists.
