I got a request for a book I posted, but there are "special requests" associated with it. One is "For paperback books, no book-crossing books". I have no idea what this means or if my book falls into that category.  Should I answer yes or no to having a book that fits this request. There is no means to ask the requestor to explain or qualify the restrictions. I'm frustrated.

Bookcrossing dot com is an unrelated site where members record their books and then pass them on (by putting them in a public place, through book swapping, etc.) hoping those that get the books will record their whereabouts, allowing them to track where the book has been. These books will either have a sticker or writing with the bookcrossing ID somewhere in the book. Most bookcrossing markings I've seen have been inside the front cover. If your book has no bookcrossing stickers or writing, it wouldn't be considered a bookcrossing book.

BookCrossing is a way of sharing and tracking books. People register their books with the BookCrossing website -- each book is given an id number and then "released" into the public (i.e., left somewhere for someone to find or given to someone). The finder then logs the book into the website. For more information, go to BookCrossing.com. Generally, PBS folks who have RCs indicating no bookcrossing books don't want them because the books sometimes have labels all over the cover or inside the cover. You will know if you have a bookcrossing book because there will be a label somewhere with the BCID (BookCrossing ID) number and BookCrossing website address.

ETA: Lsressler beat me to the explanation.

Thank you both for the reply. These were my own personal books, so I guess I don't have to worry about it.
