Each result in LibrarySearch identifies the type of item: book, e-book, journal article, video, etc.
Items that are available online have a Full Text link. Click it to access the item.
Books, videos, and other items that are in the Library have a link called Check Availability. Click it to see which campus library holds the item, where it is in the Library, and whether it is on the shelf or on loan. You can request items that are at other campus libraries, or are on loan to someone else.
You may have a reference for an article that does not have a Full Text link. The Availability information says Citation Online. In these cases, the Library does not have access to the full article, it only has the details you see on the screen (when and where the article was published). Click the title to get to a screen that lets you request the article on Interlibrary Loan.
