I have a collection of about 3,000 classical LPs. They are generally ordered chronologically by when composed. Hence, medieval, renaissance, baroque, classical, etc. Bach before Haydn before Mozart before Beethoven, etc. Vocal and opera recordings are segregated from instrumental but are also arranged chronologically.
Recordings by the same composer are ordered: symphonies and other large orchestral works; concerti; chamber works; solo instruments. It's far from perfect, but I can usually find what I'm looking for very quickly.
