Sure! It's not reaaaally the library but it's where Twilight sets up shop!

[Oh hey there's Twilight's Castle just over the ridge. Pinkie bounces towards it.]

There's a huge library and I'm sure you can talk shop with Starlight Glimmer who used to be this evil brainwashing cult leader but hey, that's just water under the bridge now. She's Twilight's second student cause the first is in an alternate reality through a magic mirror full of humans!
