One of the primary functions of a library is to be a place (whether in a physical location or online) where knowledge is collected, organized and made accessible to its users.
This video from the Community College of Vermont describes the reasons for using library resources for academic work. (5 minutes)
The Library website is the primary gateway to all of the Library's resources, including the catalog to find physical books, magazines, films and maps in the library, as well as links to electronic databases providing thousands of full-text articles, streaming films, images, and electronic books.
Don't confuse the medium with the message. The Web is the delivery platform, not the content of the library pages you view. Most of the full-text text-resources are not freely available to everyone on the Web, but require a current affliation with the UH System. The UH Libraries pay for the subscriptions to these academic databases, which are part of the "deep web", just as they pay for books and magazine subscriptions on the library shelves.
