I'm a bit confused, because I had thought the algorithm worked such that every page of text would be unique, but that's not the case. There are many books that contain exactly the same page of content. It's easy enough to verify if one simply types in a full 3200 character long string, searches for it, and pulls up all of the exact matches.

Was the intention to have unique books rather than pages? But if that were the case, wouldn't that mean the site is actually giving us every possible combination of 410*3200 characters?? Any help for me to better understand what's happening here would be much appreciated!
