Prior to the Wörterbuch der ägyptischen Sprache, but nothing brilliant with respect to use of a zettelkasten to create.

Watts, Charles J. The Cost of Production. Muskegon, MI: The Shaw-Walker Company, 1902. http://archive.org/details/costproduction01wattgoog.

Short book on managing manufacturing costs. Not too much of an advertisement for Shaw-Walker manufactured goods (files, file management, filing cabinets, etc.). Only 64 pages are the primary content and the balance (about half) are advertisements.

Given the publication date of 1902, this would have preceded the publication of System Magazine which began in 1903. This may have then been a prototype version of an early business magazine, but with a single author, no real editorial, and only one article.

Presumably it may also have served the marketing interests of Shaw-Walker as a marketing piece as well.

Tangentially, I'm a bit intrigued by the "Mr. Morse" mentioned on page 109 who is being touted as an in-house consultant for Shaw-Walker.... Is this the same Frank Morse who broke off to form the Browne-Morse Co.? (very likely)

How to Run a War Chest Campaign. Rochester, N.Y.: Yawman & Erbe Mfg. Co., 1918. http://archive.org/details/howtorunwarchest00yawm.

Broadly a manual on how to do a big community fundraising effort. Emphasis on furniture and filing systems that could be purchased from the publisher of the piece.
