"Neal Wyatt's book has chapters recommending books about sports, travel, true crime, true adventure, memoirs, history and biographies, 'general nonfiction', whatever that is, and so on. Science, mathematics, and nature writing are all dealt with in one chapter, as are food and cooking.
It was published in 2007, so you will not find the most recently published nonfiction in it. That is not a problem, in my opinion..."
Good review of this book, which goes on to demonstrate how the reviewer developed methods for updating.
