General instructions for using a Memindex

HOW IT IS USED <br /> Things to be done today, jot on face card. Things to be done tomorrow or next Friday, jot on card for that day. Things to keep before you until done, jot on opposite front card. A matter for January 10th jot on a short card put under the band till you return to your desk, then file next to card for January 10th when it will come out and refresh your memory.

Things to be done when in New York or Chicago jot on card "N" or "C." The new address of Mr. Jones, under "J." Ideas on advertising jot on card tabbed "adv." Things for your clerk to do, on his card , etc., etc. Retire today's card tonight, carrying forward things not completed and put next card in the file in has proved that almost back of pocket case. The alphabet enables one to index all jottings for instant reference. This system is very comprehensive yet perfectly simple. You soon the learn to depend on it every hour of every day.

Within the general instructions in a 1904 Memindex advertisement (next to an ad for "Genuine Edison Incandescent Lamps") we see the general ideas of indexing things into the future and carrying undone tasks forward, just as is done in the bullet journal method.
