I keep seeing the word "Delta" used in reference to record numbers, is this word an alternative for "catalogue" or "matrix"? Pardon my(seeming) ignorance, but I've always used the words "catalogue"(actual issue number) or "matrix"(stamper number). Over here, there was a pressing plant in California called, Monarch Record Mfg.. For every wax master they cut, they would assign a job number preceded by a triangle, which is the Greek letter, D, or Delta. Annaloog and I have a list on 45cat of the ones Anna has found. These numbers help collectors find more precise release dates for their records. So these "Delta" numbers are not in any way related to the catalogue or matrix numbers then. Is that correct? That is correct. A label may get master tapes for 5 or more singles ready at one time and send them all to Monarch (and other plants) to be pressed as singles. The labels assign their own catalogue and master numbers and the pressing plants will, likely, assign their own job numbers to each side. Not all of those singles were released at the same time, though (as far as I know). The label may have chosen to hold one back temporarily, so the Delta numbers wouldn't always be indicative of being released on a certain date. I mean, you can't claim in all cases that, say, Deltas 36241 through 36250 were all released on the same day or even week. Maybe one single in that set was held back for a month or so. So, it's not 100% accurate but it usually gets pretty close to the bullseye. Sorry it took me so long to respond, I don't come here anywhere near as often as 45cat. Plus, I've not had Internet for the past 16 months and only just got back on 2 weeks ago. I got a LOT of catching up to do!! Edited by moderator on 27th Jun 2021, 7:02 PM
