If you want to find good stuff on the Web, try these suggestions:
Read your assessment task thoroughly. What are you being asked to do? Be guided by specific instructions: 'find two definitions of networking on the web' or 'research marketing plans for local councils'.
If you are doing general background research for a topic, look for websites ending with .eduand .gov over .com. This is not a rigid rule - sometimes you'll find great material on a commercial site.
Once you've decided to use information from a website, subject it to the C.R.A.P. test! That's currency, reliability, authority, and purpose/point of view. Here is a good video clip that explains this kind of 'quality control'.
Another technique is to find an author whose work has been recommended by your lecturer. If that author has published a paper or article, check out the bibliography (reference list) to see where they get their information.
Some industry websites and professional associationsmay also have excellent information and resources. An example is the Design Institute of Australia (DIA). Their website has a 'Resources' section, as well as 'Websites of interest', articles, and news.
Look for a subject guideon your topic. To make finding relevant sources easier, librarians have put together subject guides containing books, websites, articles, media and newsfeeds.
