The Book Inscriptions Project collects interesting or odd notes written on the inside of a book. Example:

JAN. 22, 1969

dear Tim—
This glorious book has very
many weird stories in it.
It is also a Playboy book-
so when you read this book
think of the weirdest,
sexiest girl, you will think of me
Love, Gayl”

The creator of the project wonders how these books with such obviously personalized touches ended up at yard sales and flea markets. “Some of them are
so private that it seems almost impossible that they ended up in a library or a garage sale. Did the owner die, or forget that his copy of After the Fall contained a private note from his parents?”

It’s worth a look.
