Some sources are self-explanatory. If you're interested in what people are posting on Twitter about a certain subject, you might open up the Twitter app on your phone and search for a related hashtag, word, or phrase. If you want to see if there is a Wikipedia article on a topic, most likely you will search for the topic in Google or another Internet search engine and Wikipedia will be either the top result or close to it.
But other sources aren't as straight forward. We can we go to find items like magazines, newspapers, or trade journals? What about academic journals or books? Are we only supposed to use the library's databases, or can browsing Google actually be useful?
If you come across an article or book that is not in our collections, you can still get it! Just use Interlibrary Loan to request that we get you a copy of it. We'll borrow it from another library, and get it to you (usually an electronic copy) in a few business days.
It will automatically be an option in most databases, or you can fill out the form: InterLibrary Loan
