1

You doze off and waste most of the day sleeping.

2

Nasty paper cut. For the next d4 days, you suffer a penalty on rolls that require fine manipulation such as picking locks, playing music, or crafting.

3

You must pay a small fine for not returning the books in a timely fashion or for some other offense.

4

The information overload fries your brain. You suffer a penalty on knowledge and intelligence rolls until you go a whole day without making any.

5

You caused an incident that got you kicked out of the library and banned for 2d6 days.

6

You lost or ruined the only book(s) on the subject that you were researching. The library imposes a hefty fine.

7

You get your facts confused. From now on, whenever you try to recall information about the subject or do further research on it, the GM secretly rolls a d6 and gives you incorrect information on a 1-2.

8

While reading from a book of spells (or examining a magic item), you accidentally activate its latent magic. If you have any spellcasting abilities, you cast a random spell, targeting yourself if possible.
