Follett has announced that many of its online services—including Titlewave, Destiny, and Follett Shelf—will be unavailable from Thursday, November 28, though Saturday, November 30, as the company moves its data center to another location in Illinois.

“It’s a more secure site, and it allows us to grow,” Britten Follett, publicity director, tells School Library Journal. The company is making the announcement, she says, because “we don’t want a librarian to assign an ebook project over the weekend and have students not be able to access the services.”

The company anticipates that all of its services will be restored by 6pm CST on Sunday, and advises its customers to visit FollettUpdates.com for more information.
