Are you short on time or short on funds for book buying? Would you like to know what are the best nonfiction books according to the major review journals (Publishers Weekly, Kirkus, Booklist, Library Journal) without waiting for the end of the year list? Looking for something to read? You might try the Nonfiction Stars List at Overbooked. This web page lists all the nonfiction books with starred reviews in the four sources.
Looking over the page for 2006 books, I see that the review journals do not often agree. Only Orson Welles: Hello Americans by Simon Callow, Flaubert: A Biography by Frederick Brown, and The Lemon Tree: An Arab, a Jew, and the Heart of the Middle East by Sandy Tolan have been given a star by all four journals. Most other have only one or maybe two stars.
This Overbooked page is worth a bookmark.
