Vinyl records - where to dig?

Looking for EDM. 80's, 90's, 00's, all of it.

Let It Be closed in late 00's...

Cheapo uptown closed a couple years ago... Among others (other cheapos, genre specific places like VitalVinyl)

So where did the actual records GO? Into the landfills?

There must be warehouses and storage units full of old gold around here. So.. Where? Does anyone know if it is gone?
