The American Library Association announced its finalists for the second annual Andrew Carnegie Medals for Excellence in Fiction and Nonfiction yesterday. The three nominees in fiction are Canada, by Richard Ford, The Round House, by Louise Erdrich, and This is How You Lose Her, by Junot Diaz; the three nominees in nonfiction are The Mansion of Happiness, by Harvard historian Jill Lepore, the medical science thriller, Spillover: Animal Infections and the Next Human Pandemic, by David Quammen, and Timothy Egan’s Short Nights of the Shadow Catcher: The Epic Life and Immortal Photographs of Edward Curtis. The winners (one for each category) will be announced at ALA’s annual conference in Chicago June 30th. Founded in 2012, the award is co-sponsored by Booklist and ALA’s Reference and User Services Association (RUSA). Last year’s prizes went to Man Booker Award-winner Anne Enright for her novel The Forgotten Waltz and Pulitzer Prize winner Robert K. Massie for his biography of Catherine the Great.
