Of the five evaluative criteria listed in Evaluating Information found on the Internet, three may be investigated by electronic means:
This document will give you a variety of ways to look for each kind of information. Always remember that there other, nonelectronic, methods of getting much of the information discussed in this document. Visit the library and ask a librarian for help.
If you can answer "Yes" to the first question only, you may need to find further information on the author. There are a number of ways in which you might do this:
1. Go to the home page of the web site where the document lives and search for the author's name using any available internal search engine or directory (works best for academic web sites). This may help establish affiliation.
If no information on the author can be found, or there is no signature or attribution on the page itself, go directly to...
1. A header or footer that shows its affiliation as part of a larger web site.
These features help you judge the "official character" of a web page. They act as an assurance that the page you are evaluating functions within some type of institutional setting. Judging the official nature of a web page is extremely important if the page is not signed. Some web sites do not include attributions to individual authors, so you will have to rely on your ability to evaluate the institution, or domain, where the page lives. Caveat: while the Web is looking better, especially official sites maintained at educational institutions or by scholarly societies, not everyone has caught up with the importance of consistent graphics or "return" links. So you may be looking at a perfectly good page that hasn't got any visual clues to its affiliation. Move on to the next step if this is the case...
If your page gives no clues as to its identity, you will need to focus on the URL, or address.
1. Can you find the web site's home page by deleting all the information in the URL after the server name?
Once you find the name of the organization owning the server, you may have enough information to judge its reputation as an information source. Remember, this is only of value for official pages from a web site. If the page you are evaluating comes from someone's personal account, you really have no idea what their place is within the organization, or if they are in a position to represent the organization. If you are not familiar with the organization, try one of the following:
1. If it is an association of some kind, look for it at The Scholarly Societies Project. Is it represented?
Why might an author or publishing body want to remain anonymous? Read Information and its Counterfeits: Propaganda, Misinformation and Disinformation to learn why...and to understand why you need to know where "information" comes from.
If you cannot ascertain either the author or publisher of the page you are trying to evaluate, you are looking at information that is as anonymous as a page torn out of a book. You cannot evaluate what you cannot verify. It is unwise to use information of this nature. Look for another source.
Currency (of the document itself)
1. Does it use a caption such as "Based on 1990 US Census data"?
If you cannot ascertain where the statistical information comes from, or what its age is, you are once again looking at anonymous information.
It is also valuable to know when a page was last updated. Has it been "pruned" or "dusted" lately, or has it been sitting on the shelf?
1. Look at the bottom of the page. Does it have a "last updated" date?
It's valuable to know the age and updatedness of your page because you may be looking at an orphaned or superseded document that has been replaced by other information.
Always remember that the best counterfeit looks the most like the real thing. How genuine and trustworthy is your information?
