Fall 2007 I was the TA for a MASS
course taught by Anatole
Katok under the title "Surfaces:
(almost) everything you wanted to know about them."
From that experience was born a set of course
notes, which after some extensive polishing and
reworking was published in book form by the American
Mathematical Society. The initial
draft is still posted on the course website,
with all its errors, omissions, and countless rough
spots which were smoothed out for the book itself
(along with all those which weren't).
Prof. Katok has a website
with more information about the book, including
excerpts. The book has now been published, and
is available through the AMS,
and of course through places like Amazon.
