There is a lot of good stuff contained in the Problems section of the American Mathematical Monthly. One difficulty with extracting that information, however, is that if I see an old Monthly problem, it is not always so easy to locate the solution. Sometimes the solution does not appear until many years later, and in some cases the solution has never appeared at all. For those at an academic institution with access to JSTOR, sometimes an electronic search will turn up the solution, but if the search comes up empty, I am left wondering whether the solution was really never published or whether I just did something wrong with my search. Furthermore, even with JSTOR access, there is no easy way to list (for example) all unsolved Monthly problems.
Does anybody have, or know of, an index of all the Monthly problems and solutions that would address this issue? Failing that, is there any interest in creating such a publicly available resource? If the work is divvied up among a few dozen volunteers it shouldn't take that much work. As I envisage it, the index would (at least initially) not contain the mathematical content of the problems but would just give the bibliographic information for the problem and the solution (if any), and indicate which parts (if any) remain unsolved.
