Couldn't tell you, never tried. On my first 2 runs, I read them and sold them. On the following runs, didn't even bother to read them... just sold them. The moral to the story is, none of those books that get put in your "MISC" bag are critical to the gameplay. All the essential books are placed in your "QUEST" bag.
p.s. The items in your "QUEST" bag DO NOT count towards your item limit.
