As a life-long record collector, the name Joel Whitburn has always had a place in my mind, heart, and bookshelf.  Since 1965, Whitburn has published his Record Research books - which are considered the "bible"  in the industry, which list chart facts, figures, and data about the songs you hear on the radio.

I recently ran across this feature on Joel and his company in the Menomonee Falls Patch Business Section.  Makes for interesting reading.
