Alright cool, so this gives you options. Originally it'll take you about 55 hours to blitz through all of these books, but at the rate you're going it'll only take you 16 hours. Still a whole lot of time, and you'd be up for practically 18 hours or so just doing that, thus you'll likely be exhausted by the next day. So I'll break this down into three different choices.

You can spend 8 hours reading and get through 6 out of the 11 books. By the time you're done the afternoon bell would ring and everyone would be closing their shop and heading home or going to get dinner.

You can spend 4 hours reading and get through 4 out of the 11 books. By this time you'll be done shortly after the noon bell, which is usually lunchtime/when people go to the temple for service. You could then go do other stuff or just stay at the temple and sit in on a service.

You can spend 2 hours reading and get through 3 books out of the 11. It would be late morning by this time, around 11AM or so, so you'll still have most of the day to do whatever before people go about any notable business such as getting lunch, going to mass, etc. 

Obviously the more books you go through the more information you'll get. Not everything you'll learn would be relevant to why you're here, but some can be helpful for other reasons as well, such as learning more about how to deal with certain monsters or general adventuring tips and tricks.
