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

Consider some of the heavy duty shelving at Costco or Sam;s Club. The
product looks good, and will easily hold the weight you anticipate.
Other sources for that kind of shelving are salvage from store
remodelings, often seen on Craigslist or classifieds. Makes sense if
your talking storage and not furniture.
