 In addition to the 10 volumes on the BFD label that were reissued several times over the years, another 18 LPs and 12 CDs have been issued in the "Pebbles series" under their auspices.Many of the LPs and CDs have basically the same catalogue numbers, and there is significant overlap in the tracks on the first 6 volumes on LP and CD—with the CD release of Volume 6 being shifted to the English Freakbeat series—adding to the confusion.However, the overlap is far from complete; "Pebbles, Volume 5" is the sole CD that has all of the songs from the corresponding LP, and only about half of the surf rock tracks from the "Pebbles, Volume 4" LP were released on that CD.
