(The "lectures" do not correspond well to class sessions. There were more than 8 class meetings.) Use the notes at your own risk! I did not check them over carefully. In particular, there are many missing references. I apologize to everyone whose work went uncited.

The main references are:

"Travaux de Thurston sur les surfaces", edited by A. Fathi, F. Laudenbach, and V. Poenaru

"Mapping Class Groups" by N. Ivanov

"A geometric approach to the complex of curves on a surface" by Y. Minsky

"Thurston's notes on the geometry and topology of 3-manifolds" by W. Thurston
