A series of 42 discs containing a total of 2338 chapters, produced by CEL Educational Resources. It is excellently cataloged and cross-referenced, accompanied by six perfect bound volumes and one 3-ring binder of reference materials. Originally issued as 38 discs (disc 38 is a single side), the final four were issued as "annual updates," with the last being issued to cover up through 1989. The set was priced at $13,000, which included a Pioneer player. The price above reflects the removal of the MSLP for the player.
