The library has an extensive collection of ebooks on a variety of topics. To find what is available, enter your subject in the library catalog followed by "ebooks." For example: "supply chain management" ebooks. Putting quotes around your topic area means the catalog will search on the phrase ("supply chain management") rather than each word separately.
Almost all of the library's ebooks are multi-user. This means that your whole class could access the book simultaneously and for free!
