## Homotopy Types

This 72 page article, by Hans Baues, is to be found in the Handbook of Algebraic Topology. It starts from a basic position and attacks three main topics:

• Homotopy types with non-trivial fundamental group (Sections 2 - 5);

• Homotopy types with trivial fundamental group (Sections 6 - 9, 12);

• Stable homotopy types (Sections 10 and 11).
