Authorised BMP Books

Just a simple question: what is the limit on authorised copies of BMP books, and is this limit imposed per character or per account?

if I recall correctly you get one for each time you finish the mission, but you can only get one for each discovery you make on that character. So after all discoveries are found you can only get one per mission.

So there is technically no limit on them?

Correct. If you don't care about the discoveries, you can just do the missions over and over again for a book and cash reward each time.

Okay, thanks--I must have ended up getting the BMP with the promotion (spend more than x dollars in the in-game store and get it free, wasn't it?), but I didn't realise that I had it until I checked my access keys. I just wanted to see if there was any limit to the amount of authorised stories I could get before I started cashing them in.
