The volume includes many of the pop music surveys from the 1980-1984 period. Like the other radio charts titles, my goal was to provide a convenient chronological compilation of weekly surveys with corrections of the considerable errors found in both the original sources and in translation to online sites. These radio charts – which exist in the public domain – can be found in a multitude of sources, including original published sheets distributed via retail outlets, mail inquiries, etc., notation of on-air broadcasts, back issues of area newspapers (where stations are located) and music trade periodicals, specialized reference books, and websites interested in historical documentation, most notably, Oldiesloon, musicradio77, and ARSA. I employed multiple sources in the compilation of each radio chart volume in order to provide the most accurate data possible.
