Curious record side labeling


Do any of the jazz gurus on here know why some double-set records have this curious side labeling where record 1 has sides A and D, and record 2 sides B and C? It does not make much sense to me, and I wonder what purpose it serves other than to confuse the listener. I noticed this with a couple of Coltrane records from the '60s, recently with "The Other Village Vanguard Tapes."

It wasn't only with jazz. I've got a copy of "Layla and Other Assorted Love Songs" with the same arrangement, and I remember having some other rock and roll double albums back in the day that had sides 1 and 4 on one disc and 2 and 3 on the other. Don't recall the last time I saw a record changer, though.

I did not know this. We should try to learn something new everyday. Well, I did today. Thanks guys!
Thanks guys. I suppose it makes more sense now, but I'm still surprised that record companies would label sides with LP changers in mind, rather than what made more sense for standard turntables, which surely outnumbered changers by a wide margin.

The only advantage to automatic sequencing is that it can be handy for listening to some operas. There are a few that have interesting opening material and great endings with a lot of "filler" in the middle. If you can just flip over a record to go from side 1 to 4 or 1 to 6 or 1 to 8, that might be an advantage--I might do that with, for example, Der Rosenkavalier."
