A List of Things to be Read

There are a few topics that I'm interested in reading about, but haven't got any books on yet. This post will serve as a repository of these topics (so that I don't forget about any of them).

• Conceptual Mathematics: A First Introduction to Categories is on category theory (Jon Cohen recommended it to me)
• Sets for Mathematics does sets (of which I have only an informal understanding)

More will be added as the need arises.
