Q: What is Lean Library and how do I use it?


Lean Library is a browser extension that tells you when the KSU Library System can give you free access to an article or book.

  • Go to and download your browser’s extension (i.e. Firefox, Chrome, Safari, Edge, etc.).
  • Click on the button titled “Add to [Web Browser of Your Choice]."
    • Note that the extension you download, should mirror the web browser you are using.
    • Once the extension has been added to your browser it will appear as a button titled LL.

  • Activate your KSU credentials by using DUO to log into either the library’s SuperSearch database or your KSU email.
  • Navigate to your preferred search engine (ex. Google,, etc.) and click on the LL button to activate the extension.
    • The extension will only be active while you are on this website.

Common Questions

Does Lean Library tell me if we have access to physical books?

  • No, Lean Library will only tell you if the library has an electronic copy of a book.

Can Lean Library tell me if we have access to a different version of a book?

  • No, Lean Library connects you to the specific copy of the book that you are searching for. It cannot find older or newer versions of that book.

Will Lean Library automatically turn on?

  • Yes, it will show a pop-up box on the top right-hand side of your browser when it has located an item in our collection. It will work better if you sign in first at and leave that tab open while you are searching for research articles and e-books.

Can Lean Library give me access to newspaper articles?

  • It may direct you to newspapers that we subscribe to, but it may not locate specific articles. This behavior is because newspaper articles do not have a unique identifier, such as a DOI or ISBN.
