A product space X×Y is said to be strongly rectangular [2] if every locally finite open cover of X×Y has a locally finite refinement by cozero rectangles. A space X is said to be base-paracompact [1] if there is a base B of X with |B|=w(X) such that every open cover of X has a locally finite refinement by members of B. We simultaneously discuss strong rectangularity and base-paracompactness of product spaces. In particular, we have solved [2, Problem 2] affirmatively.
