_____________________________________

Up to around 15 minutes of audio per side does not fit to the LP format, it is a more loud cut.
LP means Long Play microgroove cut. It allows to engrave up to approximately 30 minutes per side on a 12".

Discogs database discriminates between those two formats (see RSG §6.6).
Thereby, even if labels' marketing communication could sometime use 'LP' to notify that the release contains the usual amount of audio for an album, It should be understood as 'Long Playing release', not as 'Long Play cut'.

For example here is two different cuts for the same album:
-Original LP release: Roots
-Same audio material later distributed on a 2X12" 33RPM: Roots

RP means repressed with a master originated from a lacquer that has been used previously, it should only be ticked by providing a link to a previous version sharing the same runouts, or at least a strong source. If none of this information is provided, RE is enough, moreover RE + RP can be used together, if there is a significant time gap between releases.
