Reported is an initial attempt to define a minimal college mathematics library. Included is a list of some 300 books, from which approximately 170 are to be chosen to form a basic library in undergraduate mathematics. The areas provided for in this list include Algebra, Analysis, Applied Mathematics, Geometry, Topology, Logic, Foundations and Set Theory, Probability-Statistics, and Number Theory. The intended goals of this basic collection are to (1) provide the student with introductory materials in various fields of mathematics which he may not have previously encountered, (2) provide the interested students with reading material collateral to his course work, (3) provide the student with reading at a level beyond that ordinarily encountered in the undergraduate curriculum, (4) provide the faculty with reference material, and (5) provide the general reader with elementary material in the field of mathematics.
