Basic Topology of 3-Manifolds

Free book “Basic 3-Manifold Topology” by Allen Hatcher can be downloaded in pdf and postscript formats. The three chapters here are to a certain extent independent of each other. The main exceptions are that the beginning of Chapter 1 is a prerequisite for almost everything else, while some of the later parts of Chapter 1 are used in Chapter 2.
