The pocket notebooks are a group of miscellaneous books, generally measuring about 3 to 4 inches in width and 6 to 7 inches in height. Included among the pocket notebooks is a set of six journals kept by Charles P. Mott between March 1880 and March 1881 to record daily activities at the Menlo Park Laboratory. The entries in these books were later transferred, sometimes in expanded form, to Menlo Park Notebooks #53 and #117. The other pocket notebooks are by Edison and Charles Batchelor. The entries relate to a wide variety of topics, including electric lighting, telephony, telegraphy, the phonograph, and hearing aids. Courtesy of Thomas Edison National Historical Park.
