Browser Extension - LibKey Nomad

LibKey Nomad is a browser extension that simplifies and streamlines access to the Purdue Library's subscription resources.

How To Use

LibKey Nomad in Action

When you land on a page for an article, LibKey Nomad automatically checks against the Purdue Library's subscriptions and provides a link to:

  • PDF of the article, if available
  • Manuscript version (via Unpaywall), if available
  • Link to request full text, if full text is not available

If you are off campus you will be directed to authenticate with BoilerKey before being taken to the PDF of the article. LibKey Nomad does not store your credentials or require you to create an account.

What to look for

LibKey Nomad automatically places a button in the bottom corner of a compatible webpage. This button changes its appearance to indicate what level of access is available.
