Keeping things like this are done but those that are very careful to keep things save. It might not really make the full meaning in English though but trust me, it's making a whole lot of sense after reading it all.. I sometimes love to read old books because they make sense when reading.
As time passes, this book gets more and more interesting. Reading some of the texts gave me a little idea of how people used to have fun through those writings :D
Wao! I love the fact that you were even able to keep things like this for record-keeping purposes, and I am sure more people are still going to gain knowledge from this book.
