Known issues
This system is better and comfort for me, than digital. But I have never think system is perfect. Followings are problems I understand at current state, with 4,000 of indexcard.
- How to reduce cards : I don’t know what happen if I use this system for 2 years or more without reducing cards. Discard, or I should keep everything. How to write, how not to write.
- Time stamp for GTD card : I have been thinking ver. 2 still have problem. Which time stamp should be used, a time it was written or a time it is accomplished.
- How to search a card quickly : As number of card increase, it become more and more difficult to search a card I want. Or I should quit search.

What do you think of using the Noguchi filing system for indexcards?

Quit search? If you’re considering doing that, it sounds like you should scan them all into the computer or get someone to input them for you, even if it does tike time and money.

Regarding Timestamp for GTD card. I think it should be organized by time WRITTEN, so that you know where it belongs before completion, and it will always be in the same place, from the time it was written to the time it was completed. Also, it is possible that a GTD card will never be completed. It seems that the Completed timestamp is more like Extra information, than Core information for cataloging.

I think noguchi filing system works for a hundred indexcard. But not for more than thousand. It is difficult to keep whole of my indexcard system alive.

Scanning indexcard is done by a person exactly your above. See Dave’s flickr photo set “Index cards“.

I think your way is simple and consistent. It keep system rigid.
