It can also be done using a few small books, mapping strings of 4 base 64 characters into 3 ASCII characters. With 100 printable characters (according to Python), and assuming you can get 96 per page (4 columns of 24; possible with clever layout), that would fill about 50 books.
Okay, maybe that's not very efficient.
Each pair of Base 64 characters contains a single ASCII character, plus some change. That would take three lookup tables of about 1000 entries each; given that the “change” letters could use character ranges, that would take 3 or 4 sheets of A4 (or A3, if you wanted large print).
