Is there any published summary of Erdos's published problems in the American Mathematical Monthly journal? As we know Erdos has proposed a considerable number of problems in the "American Mathematical Monthly" journal. Is there any published summary of Erdos's published problems in the American Mathematical Monthly journal?  
Thank you!
 A: I do not think that anyone ever made an effort to collect ALL problems of Erdos.
In the later part of his life he liked to give talks on various conferences under the title "My favorite unsolved problems" (I recomend typing this on Google, there are many versions). But usually these collections were selected according to the topic of the conference.
EDIT. In general, his problems are widely scattered. In the last years of his life he was mostly interested in graphs and combinatorics. But I know, for example, a collection of Erdos's problems in complex analysis dated 1964, and included in the book of W. Hayman
"Research Problems in Function theory". This example shows that it would be very difficult to collect them all. A person searching for "Erdos problems" is unlikely to find a book like this.
A: I do not know of such a summary.  But JSTOR has spent considerable time indexing the Monthly, including the "Problems and Solutions" sections.  So if your library has a JSTOR subscription you can search for these.  (Access it on-line through your library.  Or in person on a terminal at your library.)
Searching Author Erdos and Publication Title American Mathematical Monthly, I got 304 matches.  Some of those may be actual articles by Erdos, but most of them are solutions in the Problems and Solutions section.  If Erdos was the proposer, it should be indexed in this way.
For example, May 1961:
