For the serious record collector, this book covers the history of three Billboard music charts: "Bubbling Under the Hot 100," "Bubbling Under the Top Pop Albums" and "Best Selling Pop EPs." Includes an artist-by-artist listing of all 5,535 singles that hit the "Bubbling Under the Hot 100" chart but did not advance to the "Hot 100," with complete chart data, B-sides of all singles, and artist and record notes. The Bubbling Albums section provides full data for every album on Billboard's "Bubbling Under the Top Pop Albums" chart that did not climb to the Pop Albums chart. Also includes info and record jacket photos of all 131 EPs that appeared on Billboard's "Best Selling Pop EPs" chart, from 1957-1960. These 7" mini-albums with picturesque sleeves are now highly prized by collectors. 416 pages, 7" x 91"
