Umm, there are around 400 poems, I believe, about 100 or so unpublished.

My listing, which I haven't revised in quite some time, has 713 entries. About 50-70 of these are for variants I would say. This listing includes all of the poems I know of, including the entirety of those found in the Tevis Clyde Smith letters (over 200).
