Jonathan Karp will be a guest on Talk of the Nation this afternoon. Karp wrote a piece recently for the Washington Post in which he asserts that there are too many books, and many of these books are no good. This is one reason I started What to Read Next: as a means to identify great reading from the huge inventory of books available, many of which are not worth reading. I'll be interested to hear what Mr. Karp has to say. If you miss the show but want to hear the audio, check out NPR's web site.
