Found Lonely Planet guide near Central Library

I found a travel guide this afternoon around 3:15 PM outside the San Diego Central Library on Park Boulevard. It's a pocket-sized Lonely Planet Mexico & Central America paperback, blue-and-white cover, with a blue ribbon bookmark that has a tiny compass charm attached. The spine is creased and there’s a light coffee stain along the back cover, plus a couple of pages dog-eared with a rough travel itinerary. It looks well-used but still in good shape, and I figured someone might be missing it and could use it for their trip. If it matches, I’m happy to return it to the owner.
