During this weekend ProQuest will be undertaking product maintenance to upgrade infrastructure, enhance security, and maintain reliability of their products. This vital work will mean that ProQuest databases and RefWorks will not be available for a limited time during the morning of Sunday January 28, if you are based in the UK.

United Kingdom (GMT): Sunday, 28 January, 3:00 a.m. through Sunday, 28 January, 11:00 a.m.

If you are based elsewhere in the world you can check here to see when the maintenance will occur in your region.

While the date and time were chosen to minimize impact ProQuest realize that some users may be affected, and apologise for the inconvenience.
