What is Indexcard anyway?
So called "Indexcard" is 5 inch x 3 inch (125 mm x 75 mm) size paper. 6 inch x 4 inch and B6 size indexcards are also available in Japan. The 5x3 size card have been used in library, and the 6x4 and B6 have been used by researcher for long time.

Recently, indexcard is getting popular and popular. I think two events become a break-through for new era of indexcard. One is Jazzmasterson's photos on the flickr about combination of indexcard and GTD (ver. 1 and ver. 2). Another is Merlin Mann's "Hipster PDA" in his site "43 folders".

It is curious for me that analog paper is getting popular and popular in this digital high-tech world.
