On October 25, 2017, the link to the Classic Catalog will be removed from the Library Homepage. If you want to access Classic Catalog after that date, please bookmark its URL: http://catalog.library.duke.edu (click to proceed to Classic Catalog).

Why will this happen?

The Library's Classic Catalog interface was built in an earlier era and relies on the HTTP protocol rather than HTTPS; because of this, Duke University Libraries is removing the link to Classic Catalog from the library homepage.

HTTPS, which means Hypertext Transfer Protocol Secure, ensures an encrypted connection, providing greater privacy and security than the HTTP protocol many sites have previously used.

Can you continue to use Classic Catalog, anyway?

You may continue to use Classic Catalog "as is," but depending on which web browser you use, you may see a "Not Secure" warning when you type search terms into the search box.

This warning appears because newer web browsers take a more security-conscious approach. Nothing has changed with Classic Catalog, it is the same as it has been for years, it is simply an older web application that is not built to current standards.

Are there alternatives?

As an alternative, we encourage you to use either the All search or Books & Media search which are available on the homepage search box.
