You can request a library item be held for pick up at the library of your choice when it becomes available. Physical items in your catalog search results have a Place Hold button. If you are not logged in to your account, a small login window will pop up. When logged in, you will be able to choose the pickup library for your hold. Digital items may be held through the app used to access them. 

The Place Hold(s) option can also be found in the Select an Action dropdown list on item detail pages and popups.
