BookSense.com [6] sites will experience significant downtime this weekend as a new production database and server are brought online. When completed, the upgrade will result in increased speed and stability for participants' Web sites. Most of the downtime is expected to occur during the first half of Sunday.

During this period, consumers will not be able to access BookSense.com sites, and booksellers will not able to access their BookSense.com Admin page. In both cases, users will be presented with a "maintenance page," instructing them to return later.

Booksellers with questions about the BookSense.com upgrade should contact BookSense.com DirectorLen Vlahos at [email protected] [7].
