The Gutenberg Bible and the Need for a New Census

Whenever someone was to give information of the Gutenberg Bible, they would give you a Census. The problem was that they used their own numbers. It has always been hard to understand each Gutenberg Bible. My Book is trying to understand that the numbers used for Census, should give the number when they had been found. The fist Gutenberg Bible found was the Mazarine Library. It should always be called #1. The Gutenberg Bible at Berlin, Germany was number #2. That is how a Census should use it. It is very special that in 2008, I have found 50 Gutenberg Bibles.
