Dear ProQuest customer,

We have discovered an unanticipated opportunity to enhance the ProQuest庐 online information system that will improve performance and further enhance ProQuest's reliability. To install these modifications, we are scheduling a maintenance window during a low-usage period. The maintenance window will begin Thursday, May 4, between 2:00 am and 3:00 am EST.

The following products will be unavailable during this brief window:

• ProQuest庐, including ProQuest interface products, ProQuest Historical Newspapers (traditional and graphical K12 interface), American Periodicals Series
• Third-party databases such as CINAHL庐 Database with Full Text
• ProQuest Archiver
