A Reference Source is usually a physical or digital document that you would refer to for more information about a topic. When doing academic research, it is sometimes much better to consult a reference resource than to type your question into google. Reference resources are usually curated around specific topics, making them more credible and informative than the advertisement suggestion that will pop up at the top of your google search!
Examples of Reference resources:
Selected books, journals articles, and reference books published by Cambridge University Press.
Encyclopaedia Britannica Public Library Edition.
Online encyclopedias, dictionaries and other reference books on all subjects, published by Oxford University Press.
Note that in CrossSearch, many topics, events, groups, etc., have a "Research Starter" entry at the top of the results. This is a great way to get started, often with timelines, jumping-off points for other references, and important terms and themes in that topic.
We have many physical reference books such as encyclopedias and atlases in our physical collection at Dinand. Any books labeled as "Dinand Reference" are available on our reference book shelves in the Dinand Reading room. You would locate these books by using the book's call number to locate it from the reading room reference shelves. Other books on this list are available in our physical stacks in Dinand or as ebooks. To locate physical books, feel free to ask our staff at the Dinand circulation desk for help!
