INTRODUCTION This fascicle consists of the Notes of a course given at the University of Chicago in 1954. the purpose of which was to discuss some then recent developments in the homology theory of fibre bundles. pertaining to H-spaces. spectral sequences. classifying spaces and characteristic classes. Since then. of course. alternative approaches to some of these topics have been introduced. and new results have been obtained. which make: these Notes outdated in several respects. In spite (or maybe because) of this. it was recently suggested that they be included in this series. No changes have been made in the original version. written by E. Halpern. to whom I am glad to express my hearty thanks. However. some comments have been added at the end. which. without aiming at completeness. point out further results and give more recent references. A. Borel
