That is just a website demonstrating the concept of a famous science fiction story. Everything I said above remains true.
- No storage can hold that. Its likely a computer generated system.
- Any computer generated set of text cannot be copyrighted.
Finding any particular book in that "library" would require an index that is the same length / entropy as a full length book in any case. So its a stupid thought experiment to any information theorist. (I'm a Comp. Engineer by trade and have been taught numerous theoretical comp. sci. problems from Nyquist Frequencies, theories on communication, entropy and other such concepts. So this is actually well within my wheelhouse, training an expertise).
Go search for a book in there that replicates Shakespeare's Hamlet in its entirety. The only way that website could possibly work is if the link you give me has the same entropy / information space as all of Hamlet to begin with.
In the case of copyright law, the Website's code (including its text generating engine and so forth) is subject to copyright. But the Quadrillion-pages of "text" (most of which is random-gibberish) is not copyrightable.
