Dearlaura and Jeff: Some guides to Pound that I think you will find
accessible are:
Witemeyer -- for the early poems
George Kearns - Guide to EP's Selected Cantos
Michael Alexander - The Poetic Achievement of EP
(with good bibliography)
But the Cantos do take some plugging -- not all good -- though
Pound said to read quickly. But you can do that only if you know
everything he knew.
