Is your feature request related to new functionality not yet included in the product? Please describe.
New. https://libraries.emory.edu/user/login is discoverable via search engines.

Is your feature request related to a problem or a change to existing functionality? Please describe.
Problem. Patrons are discovering the page via search engines and creating Drupal accounts - they are most likely hoping to log into Library Search.

Describe the solution you'd like
Permanently hide the page (adding 'noindex'?) from search engines and share the URL only with staff.

Describe alternatives you've considered
Remove the ability for none-library staff to login.

How will this impact users?
Less confusion for patrons searching for "Emory Libraries login" in search engines.
