  Editions for each quarterly rating peridod plus small market editions and special reports.
"American Radio", published by media professional James Duncan, documented the ratings of America's radio stations. Beginning in 1976, regular editions gave a snaposhot of each market's stations, their ratings formats and facilities. Editions detailed the Winter, Spring, Summer and Fall ratings periods as well as small markets. Additional reports covered the business side of radio and group ownership. 
Jim Duncan writes:
"David, I would be honored if you were to include my data on you website.  I would be disappointed if all that work, and the history it represents, were to disappear with the paper it's s printed upon."
