Recognise this?
You’re working from home and find the perfect article, but hit a paywall—even though Maastricht University Library provides access. Or you waste time navigating publisher websites to find the right way to log in.

No more. Install Lean Library or LibKey Nomad and say goodbye to paywalls and login hunts.

How do they work?
Both extensions automatically detect when you’re on a website with UM-licensed content. With a single click, you access the material through the library’s systems. Install once and enjoy simpler, faster access to the publications you need.

Lean Library – Ideal for students and general use
– Recognises licensed articles, journals, databases and e-books
– Redirects you to the correct login when needed
– Finds Open Access alternative versions when UM doesn’t subscribe

LibKey Nomad – Designed for researchers
– Provides one-click access to full-text PDFs for journal articles
– Works with databases like Web of Science, EBSCOhost, Google Scholar and PubMed, and systematic literature review tools such as Covidence
– Recognises DOIs in AI tools (e.g. ChatGPT, Claude) and research assistants (e.g. Perplexity) and creates direct links
– Note: Limited e-book support for UM users

The two browser extensions complement each other. After installation, both will work automatically. Just search and access content as you normally would on campus.
