For the research databases we subscribe to, we are contractually obligated to limit off-campus access to current Leeward CC students, staff, and faculty. Using the proxy system we use allows our patrons to use the same login and password they use for other UH services to access all of our research databases and the content within them.
If you are an instructor and you copy or download an article, and then post it or distribute it to your students without getting permission from the copyright holder, you may be in violation of copyright law.
Our vendors have paid for the content in their databases, and we pay for database subscriptions that allow students to access content from the databases. So distributing links to articles in the databases is perfectly legal.
