My husband reminded me that the used book store from this post was Alabaster Bookshop. While outside browsing the books, we met a lady walking two HUGE dogs (Scottish Deer Hounds). The dogs were VERY interested in looking in the windows. She explained that they loved watching the store's resident cat who was at the moment curled up and sleeping in the window. Awww. So if you are in the neighborhood, remember to swing by and check it out. In the past I've also found a copy of The Never Ending Story by Michael Ende and High Fidelity by Nick Hornby.

Just for fun...can you imagine two of these on the streets of NYC? Their heads were almost over the bookshelves out front:
