The dated entries in this pocket notebook cover the period May-July 1915. The book was used by Edison to record ideas about business matters, experiments to be tried, and other tasks to be performed.

Included are experimental notes pertaining to disc records, new phonograph horns, and battery cell tests, as well as numerous chemical experiments to be tried.
