Call a space base-cover paracompact if it has a base every subcover of which has a locally finite subcover. Call a space uniformly base-cover paracompact if it has a base every subfamily of which has a subfamily with the same union, and which is locally finite at each point from that union. A subspace of the Sorgenfrey line is base-cover paracompact iff it is F\sigma. A countable space need not be base-cover paracompact. Every proto-metrizable space is uniformly base-cover paracompact. A space is metrizable iff its product with a conveging sequence is uniformly base-cover paracompact. We comment on some open questions about these and other classes of spaces defined earlier by John (Ted) Porter.
