The Book of Sand is a book of infinite length. The title refers to the fact that it has no beginning nor end, like the sand of a beach.
Since the Book of infinitely long, its pages have an infinite amount of possibilities that might be written on them. Many contain complete gibberish; some, however, contain the secrets of the Infinite.
At an unknown time, Albert Roth apparently found the Book of Sand and found a page that described how to find the Aleph. It is unknown if the page he found was true or one of the many false pages the book has.
