TITLE: quadratic forms over fields of characteristic 2
QUESTION [7 upvotes]: I was wondering if anyone knows any good sources for the theory of quadratic forms over fields of characteristic 2 which are written in English?

REPLY [6 votes]: The Algebraic and Geometric Theory of Quadratic Forms by Elman, Karpenko and Merkurjev is a standard recent reference for the theory of quadratic forms, paying special attention to the differences between the theory of bilinear forms and the theory of quadratic forms in characteristic 2.
