Very admirable!
I suspect that yours is one of only a few personal libraries with such items; and, sadly, regarding Aerus-Lux's archives I'd bet that much of it was duscarded when the Old Greenwich factory was shuttered. I hate to think, too, of such ephemera being tossed when franchises close. Anyway, glad you've collected such a wide and varied assortment.
As for me, my print surface cleaner literature, mainly Electrolux USA with a few Kirby Company & Hoover Company materials, fits in a shoebox.
