Another characteristic is that the material placed on the Internet is virtually unrestricted. On most of the information, the usual quality controls, for example those of peer review, are absent. Most major libraries now all use the Internet for bibliographic control and access. One place to start a search therefore is the University of Minnesota library . Most branches of the federal and state government and, increasingly, local governments have compiled home pages and have provided various links.
Many organizations have their own pages.
A useful principle is that if an organization publishes written materials or sells a product then they also have a web page. While I encourage you to use this medium to get material for your projects, I insist on the following rules. You must cite the source of all the information you use from the Internet. After all the URL is equivalent to the book or journal article that you would traditionally use. You must also cite two dates, first, the date you visited a particular URL to get the information and second, the date the page was last updated.
