I recently listened to the best music of the last decade and have read a number of "best" lists that range from athletic feats to zany facts.
Since books are a passion for most writers and most reviewers —lists of "best books" are inevitable.
Best Fiction of the Millennium for The Millions
And if you're into language try Stephen Dobson: Language Hat
And then take a look at Philip Lopate's A Year in Reading
My best "read" for 2009—Colum McCann's Let the Great World Spin
Any books you want to suggest?
