Introduction A conference on algebraic K-theory, jointly supported by the National Science Foundation and Northwestern University, was held at Northwestern University January 12-16, 1976. These proceedings contain papers presented at that conference, survey articles on certain subspecialities represented at the conference, and related papers, some by mathematicians who did not attend the conference. The diversity of mathematical interests subsumed under the title "algebraic K-theory" is by now well-known; a glance at the contents of this volume will confirm this. To deal with this diversity, a large block of time was left free for participants to organize themselves into seminars on topics of their choice. A list of these seminar talks has been included following the list of lectures given to the full group. I have also listed the names of conference participants and of authors of articles along with their addresses as of January 1976. It seems appropriate to mention here that shortly after the end of this conference, Quillen and Sus]in, working independently, found a positive solution to Serre's problemMhich motivated some of the earliest research in the "classical" period of algebraic K-theory. Quillen's solution is to appear in Inventiones Math. On behalf of the participants, I would like to thank the NSF and Northwestern University's College of Arts and Sciences for their financial support. I would also like to thank Madalyn Kuharick and Georgette Savino of Northwestern's Mathematics Department for their excellent administrative and secretarial help. Michael R.
