Wayne -
 
  the best sum-up on what's housed at Brunnenburg is Mary de Rachewiltz's "Ezra Pound's
Library: What Remains" in Richard Taylor's/Claus Melchior's (editors)  excellent EZRA POUND
AND EUROPE, Rodopi, Amsterdam/Atlanta, 1993, pp 1-18. It's all about the BOOKS EP has read
& worked with...
 
Maybe that helps to answer yr question.
