Sometimes a quick phone call can solve a problem. Finally, I can remember how much handholding I needed to send my first email attachment or to post my first discussion item on a web board. If someone else can provide that first support when a student is stressed by getting an assignment to you, you can spend your time with content instead of mechanics. Library access is fairly self-explanatory. College librarians are used to students asking for help in getting started on research.
Online resources are just one of many library resources available to a student.
Student Support Centers can help students find resources, both print and electronic. They can provide a point of contact for interlibrary loan. It is the providing university or college who has the responsibility for providing their students with adequate library resources, but the Student Support Centers can help students with access to those resources. But they are available to get a student started. Center advisors can direct a student to the right office or phone number at another institution.
