Aeon is the electronic system you use to request an item through Special Collections as well as track the history of requests you've received previously. (Taken from this page: https://scpatron.lib.uiowa.edu/aeonauth/FAQ.html)

"Aeon is automated request and workflow management software specifically designed for special collections libraries and archives. Aeon improves patron service and maximizes staff efficiency while providing unparalleled item tracking, security and statistics.

Requests for specific items to be used in reading rooms can be made directly from InfoHawk+ by using the “Request this item for reading room use (Aeon)” links." (Taken from this page: https://www.lib.uiowa.edu/lit/services/)
