The Duke Libraries online catalog will be upgraded this weekend to the latest version of the software.  Public access to the catalog will be interrupted at 5pm on Friday, 25 May.  A backup server will be available by 5:15pm on Friday.  Patrons will still be able to search the entire library catalog during the multi-day conversion process.  However, some patron functions (notably renew, hold, and e-shelf) will not be available.  Patrons should contact their local Circulation Desk for assistance in renewals and holds during the conversion.  By Sunday evening the conversion upgrade will be complete, and all patron functions will be restored.
