Amazon.com description: Product Description: This book makes available the wealth of data contained in Cash Box's popular music album (33 1/3 rpm 12-inch records) charts over an 11-year period. This information, previously available only through a search of the weekly charts themselves, has been completely integrated and accessed via artist and song title entries. No comparable compilation covers as long a time span in one integrated volume for the black contemporary genre. The compilation contains many features not currently available in any other reference tool of its type, most notably the week-by-week listing of song chart positions. With many valuable appendixes.
