plywood deflection rating
They will sag with time. BUT if you finish both sides equally, then you can
turn them over now and then.

I'm building a wall of storage shelving for my 45 record collection (appx.
20,000). The records are stored 200/box and each box is 16x8x9, weighing
15lbs. Will 3/4" plywood shelving 4 feet long support this load without
deflecting, each shelve will be loaded to 75lbs with supports on the ends
