Chemical Engineering Catalog; Collected, Condensed, and Standarized Catalogs of Chemical Engineering, Equipment, Machinery, Chemicals and Supplies, 6th Edition

New York: Chemical Catalog Company, 1921. Thick Quarto. 1294 pages, index, illustrated and with a list of 1200 scientific and technical books available which were not in the earlier edition. The publishers used a limp leather and lighter paper so that it would not be so unwieldy. Of course, it includes many which today would be harmful not only to the environment but to the users and to those where it had been applied. Bound in flexible brown cloth lettered in black spine lettering black, some rubbing to binding. A very good copy. (Inventory #: 027474)
