User blog:Fegaxeyl/A book to change history

You have a translator, a scribe, a photocopier, a library, and a time machine. In order to change history for the better (or the worse, if you want) you can send one work or collection of works into the past. For convenience, they will be translated into all known languages of the world when you send your work back, and will be delivered to particular sites of your choice. What will you chose to send, and to when?

The rules are simple: Other than that, it's all up to you!
 * You can pick any single work (i.e. the Bible, the Selfish Gene) or a collection of works (Shakespeare, Tolkien) regardless of age, genre, and language.
 * You must say where you will send the book (i.e. the Vatican, the Senate of Rome).
 * You must say to which time period and/or date you will send the book (e.g. the Middle Dynasty of Egypt, 24th December 0AD).
 * You should give a reason why you'll send the book back and what effect you think it will have.
 * You can give as many separate suggestions as you wish, but you cannot send more than one work/group of works back in time. If you have already said you will send a postive critique on Van Gogh's artwork to him before he commits suicide, you cannot then send a study of the holocaust to Hitler's parents the day before he is conceived in the same timeline. Keep them to separate timelines.
