First, you have to create an account, which you can do here: https://usm-maine.illiad.oclc.org/illiad/.
Once you have an account you can either fill out the appropriate request forms (book, article etc.) or you can request directly from USM databases by clicking the request button.
When we receive the material, we will send you an email letting you know you can either pick it up or download it from your account.
