To renew items, you need to be signed in to get access to "My Account". (See the "Signing In" and "My Account" tabs to the left side menu.)
The "Loans" section will display the Wesleyan items you have checked out. The "Interlibrary Loan" section will list your current interlibrary loan requests and items, but you will need to click the link to "Log into your ILL account" to access articles, place or alter requests, etc.
To renew all items from Wesleyan, you can click the "Renew All" option at the top of the "Loans" box, or click to "View All Loans" at the bottom to renew items individually. Some, but not all, Interlibrary Loan items can be renewed as well.
