Whenever possible, it is very important to link to library eresources, rather than downloading the full text to share with your students.
Sometimes instructors worry that linking will make it too complicated for students to access an article or ebook, but when the correct permalink is used, the only added step is for the student to log-in with their UNCW credentials.
Feel free to use either of images below in your email signature or elsewhere (linking to this page) to help remind people to "think to link."
