This page gives an incomplete, but growing list of sources from which many problems have been compiled. Many questions and problems are obvious variations of the original one, an effort is made to list corresponding sources also. Needless to say that this task will never achieve a complete list, neverthelss it has been taken to give the credit where it is due.
The users are welcome to leave comments with regard to source on the appropriate problem page.
