Bonus Mission Pack authorized book transfer?

On the wiki it says that once you complete a bonus objective the Historian will give an authorized copy of the book to another character on your account.

I completed the bonus objective in Gwen's story where you get past each point in the cavernous area in one try, I got the extra 2.5 platinum and another authorized book for the character who I beat it with, but I don't know how to get one of the other characters on my account a copy of the authorized book?

I apologize if it was hard to follow what I said, but I only have a couple minutes to write this.

i think like the books and the actual weapons the "discoveries" are character based also and cannot be transferred

When u finish an objective he'll give u an extra book which can be claimed by any character. Talk to him, and read the choices carefully, one says "I've made new discoveries." or something similar, that's the one you want.

Damn! You were right Hoyce! Unfortunately I thought the second copy wouldn't be customized, now I have 2 copies for the character that beat it..
