Here is a modern data management challenge that Harvey solved manually many years ago. Technical journals were a very important way of keeping up to date. Harvey read or scanned many journals. We had a library of journals that was the envy of most. When Harvey read a good article he copied it put the date on the top and filed it according to the subject in his "Subject Files". The neatest things was when he read what he considered a classic, he would put a "C" in a box on the top. If any of us wanted to research a subject, we always went to the subject files first. Managing the volume of data that would accumulate over the years was a challange which Harvey solved very simply. Annually he would purge or have purged, everything that was older than three years except fo those marked "classics".
I would love to find a way of managing any of my data that I store electronically that way. I have so many old emails and I have to read them all before I delete them in fear that I will delete the classics. Any ideas? I am sure many others remember these simple systems that Harvey created for complex things.
