Hey! First of all I love the concept of the game!

I have downloaded it and spent some time wandering through, but whenever I checked one of the books they would be completely empty.

I have searched for words and phrases and it has brought me to the place I think I should be, but all the books are still empty.

All pages are loaded through libraryofbabel.info, which appears to have been down for the past couple of days.
It seems like Jonathan is working on fixing it, though:

As soon as the website is up and running again, the pages should show up in this 3D version as well. Sorry for the confusion and thanks for letting me know about this issue!
