I do send out library books, some of these books may have library stickers on the outside as well as a withdrawal stamp. My books come from a smoke free home but I do have pets. If you do not accept Exlibrary books please pm to see if the book you are requesting is an Exlibrary book. All of my books that I ship always come with a delivery confirmation number (tracking number for USPS). This will be PM'd to you once I mark the book mailed. Have a great day and thanks for looking at my books!
