My collection consists of just a modern AT and 2 pieces of garbage- but since I'm in Detroit, which I think is one of the best selections of records in the country, I've been picking from People's Records- which has a great selection of 33,45,78, from every time frame. At the moment I have around 500 records. All organized alphabetically by artist. I currently use metal record racks secured to a multi-layer wooden cabinet.
I'd be happy to post some photos of my collection if anyone is interested, In 78's collect mostly blues, jazz, swing, rags, music my great-grandpa was listening to

I don't really know much about "phonographs"- or the wind-up players 78's were originally designed for.
Anyway, thanks for this resource and sorry it took so long to join finally!
