We have a similar facility here in Pittsburgh, albeit a commercial establishment rather than a museum. Get Hip Recordings in the Manchester section of the Northside run by the always engaging Gregg Kostelich is a record store, recording studio, performance venue, and Gregg has the largest private lp warehouse I've ever seen. Think Raiders of the Lost Ark big, bins and boxes of new, unopened lps as far as you can see. A must stop for all vinyl junkies living in or visiting Pittsburgh. Gregg is also a founding member of the Cynics,a punk garage band still touring and releasing records, he also has a monthly show of traveling punk rock groups performing in the intimate venue upstairs.
I'll throw in a plug for Bicycle Heaven next door, possible the largest bicycle museum in the world with thousands of vintage and not so vintage bikes.
