Green paperback travel guide with dog-eared pages

I lost my green paperback travel guide, Lonely Planet Italy edition, yesterday around 3pm. It’s about 6 by 9 inches, with a creased spine and a coffee stain along the bottom edge. There’s a red ribbon bookmark sticking out of page 112, and the inside cover is stamped with the initials AY. I left it on a chair outside the Monroe Public Library on Main Street after grabbing a quick espresso at Cafe Verve. It means a lot to me; it was a gift from a dear friend, and I really need it back.
