Finding Books

Use the COD Library catalog to find books & videos. Click on the "keyword" tab to search using multiple search terms and limit your results by material type (book, video), date, or language. You'll need a current College of DuPage Library card to check out books.

Reference Works

Reference works, such as dictionaries and encyclopedias are useful for learning about background information on a topic. Please note that print reference books may be used while in the library only. Online reference books may be accessed from any on or off-campus computer. You'll need a College of DuPage Library card to access online books and articles from off-campus.

Click on the links below to access the online book/website or record/description of the print book.


The library has a large collection of models that can be checked out for student use at Main Circulation Desk on the second floor of the SRC. Check out our updated list of Anatomy Models. Browse by type of model or search by a specific model (AKA "stomach").


The Library owns many Biology films in DVD, VHS and streaming formats. Microscope slides for Biology 1100 and Biology 1151/1152 are also available for student use in the Library. Check the list of titles at:

The Library subscribes to many databases that provide access to thousands of popular and credible, scholarly journals. Many databases provide access to full-text articles, while some provide information about the article only (citation). Request (for free!) through Interlibrary Loan copies of articles to which the Library doesn't have full-text access.

Access the article databases listed below.
