TITLE: A reference for the Chevalley Groups
QUESTION [7 upvotes]: Hello everyone
I would like to learn basic theory of the Chevalley Groups. There are several references for this subject, like "Introduction to Lie algebras and representation theory" by Humphreys, and Steinberg notes on the Chevalley groups. 
Do you know any other references beside these two books? 
Thank you

REPLY [5 votes]: There is a new book: "Linear Algebraic Groups and Finite Groups of Lie Type" by Gunter Malle and Donna Testerman (Cambridge Univesity Press, 2011). The first part is an introduction to linear algebraic groups, and the third part is on finite groups of Lie type).
