Q. Does Krueger Library have a search tool to avoid paywalls in Wikipedia and Pubmed?

Yes, we have LibKey Nomad from Third Iron. It provides inline links to WSU holdings. When we do not have direct access to the article, you will be routed to a Resource Sharing request form. 

This can be added to your browser on a personal or WSU issued device.
