The UAH Library catalog will be down for maintenance this evening, beginning at 4:30 pm. While there is not an exact timetable for the work to be completed, we hope to have access restored in a few short hours. As a partial work-around to this issue, you can also search for books and other materials via the OneSearch tool on the library homepage at uah.edu/library. OneSearch actually allows you to retrieve books in addition to periodical materials, so if you find yourself needing to locate a book (in print or electronic form), OneSearch has you covered. Thank you for your patience!
