These are two fascinating books about items left inside books .
Years ago, using the bookmark exchange addresses that year, I secretly sent out the Forgotten Bookmarks book to the readers on that list who lived in the US. I mailed it to a reader in California with instructions to insert an item in the book when she finished reading it and send it along to the next name ( label included ) on the list. Slowly that book traveled across the US, back to the Northeast and one year after I sent it out it came back to me ( the last name on the mailing list !).
Anyone here now, on that list back then ?
