This gorgeous and gorgeously produced volume entitled Emily Dickinson: The Gorgeous Nothings is a collection of facsimile reproductions of manuscript items from the Emily Dickinson collections at the Amherst College Library Archives & Special Collections. They comprise her jottings on envelopes or scraps of envelopes, and are almost all in pencil. She apparently found a small stub of pencil (the image of one is included in the facsimile reproductions in the book) so easily tucked into a pocket as to be handy at any moment when words came to her.
Each scrap is reproduced photographically as well as transcribed. One of my favorites is on a tiny scrap: "One note from One Bird Is better than a million words"
