loginIn 1967 we prepared a collection of unsolved problems forthe Set Theory Symposium held at UCLA which finally appeared [6] four yearslater in the Proceedings of the Symposium in 1971. However, we distributed amimeographed version of the paper in 1967 and since then several people workedon some of these problems and obtained solutions. We tried to keep [6] up to dateby adding remarks to the page proofs, but we believe it will be more useful if wegive a survey of the new results obtained by various people.
