tout (verb): attempt to sell (something), typically by pestering people in an aggressive or bold manner
This morning found me promoting (if not exactly attempting to sell) Wendell Berry's essay collection, A Continuous Harmony. First published by Harcourt, Brace in 1972 and subsequently by Shoemaker & Hoard (2004) and Counterpoint (2012), it is now fifty years old. The other day I pulled it from the shelf thinking that it's probably among the lesser known of his volumes, but that's hard to say. At any rate, this is what I did on Twitter.
And this was followed by a link to Counterpoint's page for the book. So I guess that I actually was trying to sell a few copies.
