Vintage educational slides / projection movie archives anywhere?

Hello, I was wondering if anyone knew of a place that had vintage educational slide decks and projection movies archived or where I could buy them. I searched eBay and only found a couple sets. I am mostly looking for those from all of <=1980s era. This is for personal use - nostalgic / memory lane. I remember when I was a child that my favorite days in school were those when we would watch slides or a projected movie from a reel. I have searched online and came up empty handed. I don't really care about the subjects of them, I would like to watch as many as possible for fun.

Thanks!
