Papers with a green background have been completely checked, and so the database should contain all problems in that paper. There remain many problem lists of Erdős that have only been partially, if at all, checked against this database. One day, hopefully, all of the problems in the lists below will have been entered into this database. One purpose of this list to show where the work remains to be done.
I believe this list is complete; if you know of a problem list (i.e. a paper (co)written by Erdős whose main purpose is to discuss open problems) not on the list please let me know.
There are 142 lists, of which 34 are completely checked.
