There's a wonderful series of books by Carlos Ruiz Zafón with this as a plot device; in the series, the "Cemetery of Forgotten Books" exists as place where forgotten books are treasured, adopted, and remembered.
Oh wow I read “The Shadow of the Wind” and enjoyed it. I didn’t know that there was a series. Thank you for the comment. I now have a few more books to search for in my local used book store.
