[Wiki] Resources for beginners to Category Theory

Since we organized our own Category Theory reading group (CTRG) in the summer of 2019, I am keeping a watch on accessible resources for beginners to category theory. This wiki page collects some of them.

Reading Material

I recently attended the ACT tutorial day 2020 and learned about the following relatively modern resources from David Spivak:



  • The broader CT community has a Category Theory chat where discussion happens at all levels. It has grown over past few months so it seems public registration is now unavailable. Contact @kartik if you’d like to be added.
  • Consider joining @CTRG for future updates and discussion. You can also email the group using ctrg@discuss.cs.uchicago.edu.

This is a wiki, please feel free to edit and improve.
