You can park anywhere in the library and Academy Square parking lot. There is also street parking.
They have parking on both sides of the library building
This part of Provo can be busy, make sure you arrive early in order to find parking. It's a beautiful venue though, I'm sure you will enjoy yourself!
There is the street level lot accessible from 500 N or 100 E, regular street parking on 100 E, street level parking accessible from 600 N, or the underground parking garage in the middle of the 100 E block which has doors directly into the library.
The parking is unfortunately small and cramped, you will have better luck parking on the street and walking, typically.
