William Lowell Putnam, a graduate of Harvard in the class of 1882, believed strongly in the value of academic competitions. To this end, Mrs. Elizabeth Lowell Putnam, the wife of Mr. Putnam, created a trust fund for supporting such competitions in memory of her husband. Two experimental competitions were held, one in English, and one in mathematics, before the competition assumed its present form in 1938. Scholarships and cash prizes ranging from $250 to $2,500 for the top students and $5,000 to $25,000 for the top schools are given by the Putnam committee.

- Math Horizons (MAA) is a magazine aimed at undergraduates with a very accessible problem section.
- Mathematics Magazine (MAA) is an expository journal of undergraduate mathematics, with an a good problem section for the undergraduate.
- The College
Mathematics Journal
- The American Mathematical Monthly publishes articles about mathematics and the profession. Its readers span a broad spectrum of mathematical interests, and include professional mathematicians as well as students of mathematics at all collegiate levels. The problem section is quite challenging, and often contains unsolved problems.
