This pocket notebook was used by Edison, probably in 1898, for notes, calculations, and drawings. The book contains a variant version of the cost and financial information recorded in PN-97-00-00.2. Also included are two versions of a proposal for a syndicate to finance operations at the Ogden works, a proposal for a "small temporary syndicate" to purchase the phonoplex business, and notes and drawings regarding mill operations and machinery. The pages are unnumbered, and the book has been used in both directions. Approximately 40 pages have been used. Courtesy of Thomas Edison National Historical Park.
