Please note that several bookshelves in the PR and PS ranges on the fourth floor of Ekstrom Library are currently inaccessible due to a concern with microbial growth. Remediation work will begin the week of Sept. 15, 2025 and will include cleaning of the affected books and shelving, ductwork, and the air handler. Until remediation work is complete, books in the affected area will remain unavailable. Other areas of the fourth floor, including books outside of the affected area, are still accessible. We apologize for the inconvenience. If you have questions, please contact Ekstrom Library.
