Like most academic libraries, ISU uses the Library of Congress Classification System to organize its books. A call number is assigned to each book or item and the book shelved alphabetically and numerically according to the call number. For chemistry, most materials are located in Library of Congress call numbers QD and TP. QD is the call number for chemistry and TP is the call number for chemical engineering.
Think! If your topic is in organic chemistry or biochemistry, perhaps the biology databases will have information for you. If your topic is in physical chemistry, check the physics databases. If your topic is health related, check the health databases. If you're investigating the chemical industry, check the business databases, too.
This site provides thermochemical, thermophysical, and ion energetics data compiled by NIST under the Standard Reference Data Program.
