Monarch & Alco Delta Numbers (LP's & 12")

This is a working list. There may be some errors and there are many missing entries (33 % complete.) Still missing 18,222, and I assume most of these are obscure Alco pressings.

The entries highlighted in yellow are duplicates and need to be confirmed.

A special thanks to readers like Phillip A., Martin K., Jacob L., Connie C., Joel C., Raymond D., and Christopher H. for providing some missing entries. And also to Discogs from where I got the bulk of this information.

If you have a missing entry and want to contribute, please message me.
