According to the text of the writer Jorge Luis Borges published in 1941.
The piece of hort story describes a library of gigantic size containing all the books of 410 possible pages (every page formed by about 40 lines 80 characters) and which all the hexagonal rooms are arranged in a identical way. Books are placed on shelves including quite the same number of floors and receiving quite the same number of books. Every book has the same number of pages and signs. The used alphabet includes twenty five characters (twenty two small letters, the space, the comma and the point).
Here, the book is quite small to make an opposite for the constructed Babel’s tower so that the summit affects heavens.
