You can search for all types of materials such as books, ebooks, articles, and streaming videos using one search box with One Search. This box is located on the Library's homepage under the One Search tab.
Below are a couple of generic videos to help you get started. In the video they say Summons instead of One Search, but it's the same thing.
If you want to find physical books located at MCC, after you do a search in One Search and your list of results comes up, limit it on the left side of the screen to Books/eBooks.
Then scroll down, click on Library Location, and limit it to Mesa CC Library.
