Two new books on noncommutative geometry recently appeared. An Introduction to Noncommutative Geometry, by J. Varilly is a short (about 100 pages) introduction to metric and spectral aspects of noncommutative geometry. Surveys in Noncommutative Geometry is edited by N. Higson and J. Roe. It is based on lectures given at the Clay Mathematics Institute Instructional Symposium on Noncommutative Geometry held at Mount Holyoke College in Massachusetts in 2000.
Speaking of noncommutative geometry books, I should mention that the main single text on the subject ( `the book') , that is Alain Connes' book, is freely available to download from Alain's website.
