It’s National Handwriting Day! The Smithsonian Field Book Project, a joint initiative between the Smithsonian Libraries, Smithsonian Institution Archives, and National Museum of Natural History to uncover, catalog, digitize, and share online the primary source records of scientific research done at, by, and for the Institution, celebrates this day with a showcase of some of the handwriting samples encountered during the project work. The Project works with materials stretching back almost 200 years, to 1816, and therefore often runs across examples of both very good and very bad handwriting.
