Allen,
If you like Williams' Paterson, I enthusiastically recommend finding a copy of James McMichael's Four Good Things. A single poem in roughly 60 pages, I think it is to the later 20th century in Modern American poetry what Paterson was to the earlier part of the same century — it also, at least in my mind, fulfills some of the promise that I think Williams held out in his own poem but perhaps never fully achieved.
Four Good Things, in its entirety, can be found in McMichael's The World at Large.
