My first job as an editor was at a weekly newspaper. My parents and I had pooled our funds (read: my college savings) and bought a couple of failing small-town newspapers. One of the things I did every week was scan other weeklies and dailies in the region and write a summary of their high-school sports coverage, citing and crediting each source, of course.
It was a different time. Back then (when I had long hair and a motorcycle), most of the publications I cited weren't generally available in my community. There were no computers. There was no Internet.
