A conference on algebraic K-theory was held at the Battelle
Seattle Research Center from August 28 to September 8, 1972, with the joint
support of the National Science Foundation and the Battelle Memorial Institute.
The present volume consists mainly of papers presented at, or stimulated by,
that conference, plus some closely related papers by mathematicians who did
not attend the conference but who have kindly consented to publish their work
here. In addition there are several papers devoted to surveys of subjects
treated at the conference, and to the formulation of open research problems.
It was our intention thus to present a reasonably comprehensive documentation
of the current research in algebraic K-theory, and, if possible, to give this
research a greater coherence than it has heretofore enjoyed. It was particularly
grati„fying to see the latter aim largely achieved already in the course of
preparing these Proceedings.
