This volume covers the period January 1878-December 1879. Most of the notes and drawings are by Edison, Charles Batchelor, and John Kruesi; a few are by John Ott and John K. Knight. Many have been witnessed by members of the laboratory staff and notarized by Stockton L. Griffin. All of the material relates to electric lighting except for a telephone drawing on page 376. Much of the electric light material for September and October 1878 has been copied into Experimental Researches, Vol.1. The volume consists of 437 numbered, unbound pages.
Several items from Vol. 16 were published in The Papers of Thomas A. Edison, Vol. 4. The images constituting these documents have been arranged in their proper sequence.
The following pages, which are missing from this volume, can be found in Laboratory Scrapbook, Cat. 1146 (Miscellaneous Shop and Laboratory Notebooks): 76, 160, 308, 387, 399.
