The Web is made up of billions of pages and web sites and is growing rapidly. The Good: • wider and easy access to information The Bad & the Ugly: • Lack of quality control - no control over who can set up a web site • Internet information can be inaccurate, out-of-date, biased and false • ‘Invisible web’ - considerable amount of academic material not available in e-form or which cannot by picked up by search engines. The Internet is not a library – there is no librarian! University Library
