This is a working list. There may be some errors and there are many missing entries. 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., and especially Joel C., and Raymond D., 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.
