Man, you guys make it way too complicated! Just kidding, whatever works. I just put my Pop (non-Classical) alphabetical by artist, then chronological. Classical alpha by composer, then alpha by piece title, then alpha by conductor. That's for both LP and CD.
Brooks Berdan had probably 25,000-30,000 LP's when he died. Sheila let him turn their dining room into his LP library. At that time I had about 5,000, and he had 5 or 6 times that. I'll bet Fremer has at least that.
