  Early in 2011 Sam Evens acting on behalf of the organizers of the summer
school on quantization at Notre Dame asked me to give a short series of
lectures on geometric quantization. These lectures were meant to prepare a
group of graduate mathematics students for talks at the conference on
quantization which were to follow the summer school. The notes that follow
resulted from this request. They are a mostly faithful record of four one-hour
lectures (except lecture 4) plus two appendices: the first one recalls bits and
pieces of category theory; the second discusses densities.
