Hours

UD students, faculty, and staff will be asked to scan their UD ID outside the exterior door before entering the library. If your UD ID is over 10 years old, please contact the Office of Safety and Security at 563.589.3333 to verify whether you need your card replaced.

Safety protocols must be observed by all users. UD’s mantra to help mitigate the spread of the virus is: Practice common sense - good hygiene, social distancing, and wear a face covering for yourself and for others.
