Best Ways to Organize a Classical Record LP Collection ?

I do it a little differently.  First, by composer, then symphonies, then major works (requiems, for example), then piano concertos, then other concertos by instrument, then sonatas by instrument, then chamber music and then smaller works.  I am intrigued by Melm's chronological organization, as it's fun to think of a work in the context of what part of a composer's life a work appeared.  Now that I think of it, in my non-classical collection, I organize by artist chronologically.  The main consideration, I think, is pick a system that will allow you to find what you're looking for.  That's especially challenging for classical, where one recording may contain works by several composers.
