Lean Library Service Discontinuation
McMaster University Libraries no longer supports Lean Library as of February 28, 2026.
The Library now provides access to the LibKey suite, which offers similar functionality for identifying and accessing full-text scholarly content online.
Users are encouraged to uninstall the Lean Library browser extension and use LibKey Nomad, LibKey.io, and BrowZine instead.
