My own opinion is it's probably best to lump all modern day 10"s (ie not 78s) in one place, otherwise it's a case of waiting for an LPCat site, then trying to work out if it's a proper LP or not (then we'll get the same arguments, only reversed !).

Many of these 10" "Mini LP's" (see also here ) are just EP's which the record companies wanted to make more attractive. If it's 15 mins long it's not really a Long Player, whatever you call it !!
