Call number ranges for chemistry

Books in Hiebert Library are arranged using call numbers based on the Library of Congress Classification system. See our guide "How to Read a Call Number" if you need an introduction to how call numbers work.

Most books in the physical sciences can be found in the following call number ranges:

     1-65: General, including alchemy
71-142: Analytical chemistry
146-197: Inorganic chemistry
      241-441: Organic chemistry
      415-436: Biochemistry
      450-801: Physical and theoretical chemistry
      625-655: Radiation chemistry
      701-731: Photochemistry
      901-999: Crystallography

 Refer to the map of Hiebert Library for help finding where these call number areas are located.

Useful subject headings

Most library users rely on simple keyword searches when looking for items in the library. While keyword searching can work well, it often provides either too many irrelevant results or too few relevant ones. We recommend that you read our guide, Getting Beyond the Keyword, to understand how to use advanced search functions and subject heading searches in the library catalog.

Every item in the Hiebert Library has subject headings attached to it, most based on Library of Congress Subject Headings (LCSH). Searching in the subject field of the Encore Discovery Service using LCSH terms will help ensure that you find resources that really are on the topic that you need. All the items in the list below are approved LCSH terms. You can learn more about how to use LCSH terms in our guide, Getting Beyond the Keyword.

While there are thousands of possible subject terms that could be used when searching for items on chemistry, the following very partial list contains some of the more helpful ones for that field. In each example below, the results come from a subject search for the listed terms, rather than merely a general keyword search. Click on any of the subject headings below to see the catalog results for that subject search.
