L.P. Cataloging Sytem Advice

I have a pleasant problem that I hope I can get some suggestions on solving.

My friend's brother just moved out of his mother's house (well he is in his 40's!). He had a large L.P. collection that would not fit in jis new apartment. He was going to throw everything in the trash but instead I offered to take his albums for the price of shipping Chicago to California.

Ten days later 27 boxes of L.P.s showed up!

This is a 1500+ L.P. collection of breathtaking ecclecticity. Everything from mainstream rock like U2, Eagles etc. to obscure rock like the Pixies, Dumptrucks, Red Lory/Yellow Lory to a nice Jazz collection to a classical (the entire Funk and Wagnals series for example) collection. Most of it in VG+ to NM condition. Breathtaking!

The question is: Rather than invent the wheel, does anyone out there with a similer type collection have advice on how to sort such a collection so it makes sense and, most importantly, one can find things????

Thanks in advance.
