I've made a new one-page pdf reference sheet, designed for Holmes but perfectly usable with OD&D + Greyhawk as well. This one compiles all of the Level 1-3 M-U spells from Holmes Basic. These are same spells appearing in OD&D + Greyhawk, plus a few new spells that Gygax debuted in Holmes and then appeared in the PHB the next year. The Holmes write-ups of these new spells are simpler than the PHB versions, so they are the closest we get to OD&D versions of these spells. #holmesref
