Eliot's Books also had a number of familiar-looking volumes, and two which clinched it: The Japan We Never Knew, by David Suzuki and Keibo Oiwa, and Japanese Inn by Oliver Statler. Those were mine, put out on the front lawn library some weeks ago and last weekend respectively. So now I know.
And occurs to me, if people are going to flog my books at Eliot's, why shouldn't I do the same and get the benefit of it?
