“The Library of Babel” by Jorge Luis Borges (1941)

[Jorge_Stolfi]

Another interesting detail is: "[a book] made up of the letters MCV, perversely repeated from the first line to the last" - the most dramatic example of a hopelessly meaningless text that has character conditional entropy equal to zero.

To be pedantic, the average character entropy would be about 20/N bits, where N is the length of the book.  The 20 bits is a guess at the size of a program that would print out that text, on the Librar'y's Official Turing Machine.

All the best, --stolfi
