Almost all of the volumes in this collection can be found at the Internet Archive. There's a lot of interisting formulas in them. I work with fertilizers and other products for agriculture and these books gave me a lot of ideas. Would be very cool if someone made a modern version of them. Although making a compilation with everything of everything would be a big problem since the American Chemical Society estimates that the number of molecules that we can create with the 118 elements of the periodic table exceeds 50 million unique compounds.
