"OK!"

The library is an enormous building with six floors, which is about as tall as any of the nonmagical buildings get. In some sections the books are chained to the walls, but for the most part there are simply people posted at the doorways to check bags and see that no one is taking books out of the library without a relevant license from the college. 

There are books on all subjects, fiction and poetry and theater and history and science and law. Most are in Kaltish, but not all; other languages have their own sections of the library on the sixth floor. There are card catalogs to help the librarians keep track of which books have been sorted where. 

It's not quite as crowded as the college's first floor, but the library is clearly well-used.

He'll just be over here in the history section for the next, oh, decade or so. Or until Imrainai tells him to leave or they close or something.

This library doesn't have a closing time; they simply change out the staff and turn on magical lamps to light the populated areas. Mahan will probably not want to sleep in the library, but additional trips can be arranged. Spite goes with him on later trips, on the grounds that Spite doesn't have anything really resembling a day job.

They have the history of the city itself here (which stretches back before the invention of writing, so the earliest parts of it somewhat are shrouded in myth and legend), which is overshadowed by the history of Kalt as a whole. They also have the histories of, according to the librarians, every nation on the face of the world, although the accuracy and completeness of the information varies widely by location and time period.

It's a great library. After a while he decides to check out their science and poetry, too.

He looks for any sign of a help wanted sign. They probably don't have one and he'll probably end up busy with sick people anyway but...

There is a sign! If he asks about it he'll be told that most library employees are required to be literate in at least two languages and to be able to demonstrate an understanding of the library's organizational system. There are also janitors, but they don't need any janitors right this moment.

Reasonable of them.

Eventually he asks if Imrainai knows whether the college did any followup research on the things he told them.
