Look for:

• Knowledgeable and acknowledged authors
• Quality control

Ask questions:

• Are the author's qualifications, such as education, profession and position stated?
• Is the author acknowledged and considered to be well-informed in this field?
• Does the author have any connections to acclaimed institutions or organisations?
• Is the publisher reputable?
• If the source is found on the Internet, who owns the site where it was published?
• Is there any information listed on how to contact the author?
• Have independent experts evaluated the quality of the information before it was published?
• Are there any grammatical or orthographic errors?

Any document on the Internet has its unique Internet address. The first part of the address is the domain. The domain defines the owner of the site. You may go step by step backwards from right to left in the address until you reach the domain. In the Internet address http://www.ntnu.no/studier/eksamen/fusk the domain is www.ntnu.no. This site is owned by NTNU.

The domain has several levels. The top level is either a country code or a code that specifies a type of organisation.

The most common codes (mainly used in USA):
.com = usually a commercial site
.edu = American educational institution
.gov = public information from American authorities
.mil = military organisation
.net = network resources and information about the Internet, etc.
.org = organisation, usually non-commercial

Codes used in the UK:
.ac = academic organisation or institution
.co=commercial organisation

Country code (every country has its own country code, but the US rarely use theirs): .no= Norway

False or genuine? Not all Internet sites are what they claim to be. Which is the official (genuine) site for The White House in USA?
