Roberta Shaffer, US Library of Congress

If you haven’t filled out your summer reading list yet, you may want to grab a pen and paper right now. And if you have, get ready to cross some of your current choices off the list. The US Library of Congress — our oldest federal cultural institution and the largest library in the world — has compiled its list of “Books that Shaped America.” In fact, this is more than a list — it’s a full Exhibition that opened just this week, and as we head into the 4th of July, it’s a perfect subject for the time. Here to tell us about it: Roberta Shaffer the Library of Congress’ Associate Librarian for Library Services. Roberta, thanks for joining us. (Originally broadcast 6-30-12 on The John Batchelor Show)
