Hi all -- I found these two links quite interesting and this seems to be the place to share them. They're both about using paper as a technology for understanding how our minds actually work and think. I believe they're more relevant to ongoing work than reference, however.
They're longish articles so print them out and read them over a cup of coffee.
An Economist article that stands up for creative clutter:
"The power of positive clutter. People don't spread paper over their desks
out of laziness. No, it represents what's going on in their heads..."
A similar Malcolm Gladwell piece from the New Yorker (note the similar anecdotes re air traffic controllers):
For the record, I use a Day-Timer but I do lust after a new Sony Clie.
cheers -- mike
