The Index to Mathematics of Computation is a compilation by author and by subject of all material which has appeared in Mathematics of Computation and its predecessor, Mathematical Tables and Other Aids to Computation, during the years 1943--1969 (twenty-three published volumes). The index contains approximately 6000 entries, and is divided into a subject classification index and an author index. The author index has been set up to give bibliographic information on all of the items published in the journal, and the subject classification index lists identifying codes that refer to the author index, thereby providing a cross-reference system that will enable the reader to retrieve information rapidly.
