The material on this page is intended to supplement the MAA's three existing compilations of Putnam exams. These books are:

- The William Lowell Putnam Mathematical Competition. Problems and solutions: 1938-1964, by Gleason, Greenwood and Kelly;
- The William Lowell Putnam mathematical competition. Problems and solutions: 1965-1984, edited by Alexanderson, Klosinski and Larson;
- The William Lowell Putnam Mathematical Competition 1985-2000: Problems, Solutions and Commentary, by Kedlaya, Poonen and Vakil.

Problem statements given here are verbatim from the competition (except some diagrams are missing), and are copyrighted by the Mathematical Association of America. They appear here with permission, but unauthorized further redistribution is subject to copyright restrictions.

Solutions given here are compiled based on numerous sources, including many
competitors; copyright is held by the named authors, who request that you
link to this page in lieu of reproducing these solutions elsewhere. Please
do not refer to these as "official solutions", as this creates confusion
with the true official solutions issued by the MAA reflecting the intent
of the problem setters. Those appear in the official exam summary,
along with results and statistics, in the *American Mathematical
Monthly* sometime in the year following the competition, usually in
October. (One typically also finds solutions in *Mathematics Magazine*
in early spring.) Results given here are taken from the summaries sent to
participating schools along with exam results; this typically occurs in
early April of the year following the competition.

For corrections and other comments, notify Kiran Kedlaya (kedlaya at ucsd dot edu).

The results and statistics from the 2015 competition are now posted. The statistics page now includes a corrected difficulty-by-problem table.
