Consider the following questions: Is it clear who developed the site? Has the author clearly provided all contact information including: e-mail address, snail mail address, phone number, and fax number? Has the author clearly stated their qualifications, credentials, or provided some personal background information, that gives them the authority to present the information on the site? Is this a person with a reputation in this field or a student posting a copy of their essay or someone sharing a point of view? Even worse, is this a cheat site? Is the site supported by a well-known organization or a commercial body? Is the information from a good quality journal or database? 2.PURPOSE The author should be clear about the purpose of the information presented in the site. Some sites are meant to inform, persuade, state an opinion, entertain, or parody something or someone. Consider the following questions: What is the purpose of the site and does the content support it? Is the information geared toward a specific audience (students, scholars, general reader)? Is the site well organized and focused? Are the links appropriate for the site? The domain of the site may also indicate its purpose.  HYPERLINK "http://www.library.dal.ca/how/url.htm" The URL can provide useful information about the type of site. 3.COVERAGE It is often difficult to assess the extent of coverage since the depth in a site, through the use of links, can be infinite. However, one author may claim to present comprehensive coverage of a topic while another may cover just one aspect of a topic. Consider the following questions: Does the site claim to be either selective or comprehensive? Are the topics explored in depth? How valuable is the web site compared to others on the same topic? Is the site filled with links to other sites rather than its own content and information? Is the site static in that it provides information with no relevant outside links? 4.CURRENCY The currency of the site refers to: 1) how current the information presented is, and 2) how often the site is updated or maintained. It is important to know when a site was created, when it was last updated, and if all of the links are current. How to evaluate a web site for currency?Consider the following questions: Can you tell the date the information was first written and when the information was last revised? Without this information, you could be using out of date information. Are the links up-to-date? All of the links provided should be reliable. Dead links or references to sites that have moved are not useful. 5.OBJECTIVITY The objectivity of the site should be clear. Beware of sites that contain a certain bias. Objective sites will present information with a minimum of bias, without the intention to persuade. How to evaluate a web site for objectivity?Consider the following questions: Is the information presented with a particular bias (very conservative, religious, socialist, left-wing, etc.) If the information is clearly biased, have you included information from other sites with a different point of view? To what extent, if any, does the information try to sway the audience? Is the site trying to explain, inform, persuade, or sell something (which can be common in commercial sites)? 6.ACCURACY There are few standards available on the web to verify the accuracy of information. It is the responsibility of the reader to beware of the information presented. Be sure to differentiate fact from opinion. How to evaluate a web site for accuracy?Consider the following questions: How reliable is the information? If the author is affiliated with a known institution, this could be a clue. If statistics and other factual information are presented, are proper references given for the origin of the information? From the reading you have already done on the subject does the information on the site seem accurate? Is the information provided comparable to other sites on the same topic? Does the text follow basic rules of grammar, spelling and composition? Is a bibliography or reference list included?
