Print reference books are on the main floor of the Carmichael Library.
Here's a partial list of print reference sources that the Carmichael Library owns. To locate these books, look on the main floor stacks that are labled "Reference." Or, you can search online. When searching in the online catalogue, you'll be able to identify reference sources by the Ref. that prefaces each call number.
If you have any problems finding sources, stop by the reference desk, which is at the main floor of the library.
