In my neighborhood people frequently leave boxes of stuff they don’t want out on the sidewalk for any passerby to take, often including books. This morning I passed by such a box and snatched up what look like three pretty good finds: Women, Earth, and Creator Spirit by Elizabeth Johnson; The Mismeasure of Man by Stephen Jay Gould; and A Whale for the Killing by Canadian naturalist and activist Farley Mowat. (I knew nothing about Mowat prior to today; I grabbed the book based solely on the cover and description.)

What a score! All three are good reads! (Maybe you’ll find Farley Mowat’s “Never Cry Wolf” on some other sidewalk. 😉 )
