Armstrong has a section of compact shelving that is not working properly, i.e. it trips the “aisle in use light” and will not clear (open). Usually we use the over-ride key but this is not working well. The section is the last four aisles of the periodicals compact shelving near the center of the stacks, call number QH 573 to the TD’s. Please if someone needs to get into this section get a supervisor or if it’s at night they’ll have to wait until morning. Get their name and the call number of the book they need , and a supervisor will retrieve it. I’ll keep you up to date as to when it will be fixed.
