Forgotten Bookmarks, by Michael Popek

This was sent to me by another Bookcrosser as part of a bookray. There had been some discussion about it on a Bookcrossing forum.

This is a compilation of strange things people have left in books to mark their places, from the early 19th century to the present day. It includes a very brief introduction, and lots of photos, all compiled by the author, a used book dealer and blogger.

I have barely started it, and am looking forward to delving further into it. When I am finished, I will send it on to the next Bookcrosser on the list.
It comes with its own collection of bookmarks, generously supplied by the one who started the bookray, and others exchanged along the way. I have added two, and removed two.
