This notebook covers the period July 1900-October 1901. It contains a list of hours worked by employees on individual projects at the laboratory. The project numbers appear in an alphabetical index at the beginning of the book. These numbers correspond to projects listed in N- 87-11-24 (Thomas A. Edison Papers, Part III (1887-1898)) and in N-01-03-15. The cover is labeled "Total Time." The book contains 80 numbered pages; the page numbers are badly faded and often illegible. Because the book is in extremely fragile condition, a photocopy has been selected instead of the original.
