Garrison Keillor: most important books

Garrison Keillor is the author, most recently, of Pontoon, his fifth Lake Wobegon novel.

He recently told Newsweek about his five most important books.

The Folksinger's Wordbook by Irwin Silber.

Hymns, blues, murder ballads, miners' laments — the whole culture.
