How to find information on all aspects of biology

Searching for Books

  • Use SouthernSearch the online CSU catalog for books at Southern and the other CSCU libraries.
  • Use WorldCat (SCSU database or website) to find books from all over the world. You can Interlibrary loan many of the books we don't have.

Biology Call Numbers

Most books and other items in the library are organized by the Library of Congress Call Number system. In that system, the basic sciences (biology, chemistry, physics, etc.) are under Q.

Biology is split among the QH's (natural history and general biology), QK (botany), QL (zoology), QM (human anatomy), QP (physiology) and QR (microbiology). You'll find biology materials in the STACKS (3rd floor), Oversized Books (3rd floor), Media (1st floor), and Reference (1st floor).


Here are the subjects associated with the specific call numbers, in case you'd like to browse. However, if you are looking for something specific, searching SouthernSearch is usually quicker.
