When you find an item in the catalog, under the Find & Request heading it might say, "Your search did not match any available resource in the PSU library." This means that the PSU Library does not own the item but can usually get it for you from another library.
In this case, you can request the item from a Summit library by clicking the "Request from Summit Libraries" link.
If the item is not available from Summit, you can request it through interlibrary loan by clicking the "Request from Interlibrary Loan" link.
