What type of information can I find on websites?
Websites can be published by individuals, companies, or organizations and usually provide specific information about topics. Websites can help you find current information and websites are easily changed and updated. Be careful when reviewing information from websites. Often times, information on websites are not held to scholarly or journalistic standards.
