The textbooks and sites listed below are (generally) available online for free (sometimes for everybody and sometimes via the U of Illinois library). You are free to purchase physical copies of the books listed below. However, note that we will reference sections in the online textbook.
This is selection. We will not cover everything in all books, but having access to a wider selection is preferable over a single author.
