What happened to the reference guide, "Hollow-Earth Theories: A List of References"?

The Library of Congress is completing a project to update and modernize Library reading room websites. As a part of the process, the Science Section has re-evaluated its web content, retiring older outdated guides, while updating and migrating more recent or heavily utilized guides to a new platform. The “Hollow-Earth Theories: A List of References” reference guide is one of several guides which are is in the process of being migrated to the new platform, but for which the process has not yet been completed.

You can access an archived version of the web feature using the Internet Archive’s Way Back Machine. 

Once the newly migrated “Hollow-Earth Theories: A List of References” is published, links pointing to the older edition will be redirected to point users to the new site.
