During the pandemic, the stacks are closed to browsing. Request delivery is the only option for accessing physical materials from the stacks.
You may place requests online via IUCAT for delivery of materials from many libraries in the IU system. Requests for items held in IU Bloomington campus libraries generally take 2-4 business days to complete. This video tutorial shows how to access and search IUCAT, with particular emphasis on how to request physical items from the libraries.
