All
registered participants are encouraged to look at problems and
solutions
from previous Putnam exams. One good source is the journal
American
Mathematical Monthly (it can be found at the UNBC library); the Exam is
usually
published in the October issue. One of the best problem solving
journals,
Crux Mathematicorum, and two other journals with nice problem-solving
sections, The College Mathematical Journal and Mathematics Magazine,
can also be found at the UNBC library.

You can also check the following sites for more info on Putnam, problems-solutions-startegies and other math competitions.

**Problem Solving Books**

For those of you who are interested to acquire a good book or two on
problem
solving, I would suggest the following (far from exhaustive) list from
Amazon.com

Math Olympiad Resources

Another list comprises all books published by the expert problem solver
Titu
Andreescu and coauthors. He has been, by far, the most active author of
problem
solving books in the recent years. He has worked on organizing math
compettions such as USA math olympiad, coaching students for
participation in the International
Math Olympiad and preparing supporting materials. He also has a book
focused
exclusively on Putnam.
