FIXME: Release 3984-25704-2 (...706-2 - ...717-2) is split across several, partly still incomplete or missing, pseudo-volumes to avoid problems with loading a 153-CD release. This is supposed to be temporary.
Exhaustive info on this box set: http://www.greatjsbach.net/etc/Bach2000.pdf (11.3 MB, 251 p.)
"Also included are a bonus CD illustrating the history of performance practice of the St. Matthew Passion and a lavishly illustrated book written by musicologist Wolfgang Sandberger titled BACH 2000: 24 Inventions on the Life and Works of Johann Sebastian Bach."
"The edition is available in four different language versions. For Bach conoisseurs who already own the complete cantatas, a box will be made available without the sacred cantata CDs but with all 12 cubes."
