How to Systematize the Day’s Work – The System Company, 1911.
(Seems to be equivalent to How to Double the Day’s Work (or this version) by P. W. Lennen) I’ve been studying personal productivity books, and this is the oldest one I own. (You can still find used copies.) It talks about how to set up a desk, how to set up files, how to use a tickler, how to create form letters. It tells how to use the handy “new” technology of the three-ring binder. It doesn’t quite add up to a unified system in the modern sense, but you can see echoes of this book in texts 100 years newer.
