The Complete Stella Library

For convenience, we here provide access to the entire library of Stella problems, organized in three ways: by mathematics course, alphabetically by problem title, and by Stella problem number. In case you are wondering how Rudd Crawford managed to organize such a huge collection of problems to be readily retrievable by topic, we have included a description of the Stella Decimal System (SDS), which allows you to find all of the problems related to a particular topic by clicking on the number for that topic. SDS also allows you to add your own problems to your collection of Stella problems by assigning the pertinent SDS topic number to each of your problems. We think you will agree that SDS is a remarkable way of cataloging a diverse and comprehensive collection of interesting problems.
