1. What can the URL tell you?

Techniques for Web Evaluation :

1. Before you leave the list of search results -- before you click and get interested in anything written on the page -- glean all you can from the URLs of each page.

2. Then choose pages most likely to be reliable and authentic.

2. Scan the perimeter of the page, looking for answers to these questions:

Techniques for Web Evaluation :

1. Look for links that say "About us," "Philosophy," "Background," "Biography", etc.

2. If you cannot find any links like these, you can often find this kind of information if you Truncate back the URL.

INSTRUCTIONS for Truncating back a URL: In the top Location Box, delete the end characters of the URL stopping just before each / (leave the slash). Press enter to see if you can see more about the author or the origins/nature of the site providing the page.

Continue this process, one slash (/) at a time, until you reach the first single / which is preceded by the domain name portion. This is the page's server or "publisher."

3. Look for the date "last updated" - usually at the bottom of a web page.

Check the date on all the pages on the site.

Questions to ask:	What are the implications?
Who wrote the page? Look for the name of the author, or the name of the organization, institution, agency, or whatever who is responsible for the page An e-mail contact is not enough If there is no personal author, look for an agency or organization that claims responsibility for the page. If you cannot find this, locate the publisher by truncating back the URL (see technique above). Does this publisher claim responsibility for the content? Does it explain why the page exists in any way?	Web pages are created with a purpose in mind by some person or agency or entity. You are looking for someone who claims accountability and responsibility for the content. An e-mail address with no additional information about the author is not sufficient for assessing the author's credentials. If this is all you have, try emailing the author and asking politely for more information about him/her.
Is the page dated? Is it current enough? Is it "stale" or "dusty" information on a time-sensitive or evolving topic? CAUTION: Undated factual or statistical information is no better than anonymous information. Don't use it without confirmation.	How recent the date needs to be depends on your needs. For some topics you want current information. For others, you want information put on the web near the time it became known. In some cases, the importance of the date is to tell you whether the page author is still maintaining an interest in the page, or has abandoned it.
What are the author's credentials on this subject? Does the purported background or education look like someone who is qualified to write on this topic? Might the page be by a hobbyist, self-proclaimed expert, or enthusiast? Is the page merely an opinion? Is there any reason you should believe its content more than any other page? Is the page a rant, an extreme view, possibly distorted or exaggerated? If you cannot find strong, relevant credentials, look very closely at documentation of sources (next section).	Anyone can put anything on the web for pennies in just a few minutes. Your task is to distinguish between the reliable and questionable. Many web pages are opinion pieces offered in a vast public forum. You should hold the author to the same degree of credentials, authority, and documentation that you would expect from something published in a reputable print resource (book, journal article, good newspaper).

3. Look for indicators of quality information:

Techniques for Web Evaluation :

1. Look for a link called "links," "additional sites," "related links," etc.

2. In the text, if you see little footnote numbers or links that might refer to documentation, take the time to explore them.

What kinds of publications or sites are they? Reputable? Scholarly?

Are they real? On the web (where no publisher is editing most pages), it is possible to create totally fake references.

3. Look at the publisher of the page (first part of the URL).

Expect a journal article, newspaper article, and some other publications that are recent to come from the original publisher IF the publication is available on the web.

Look at the bottom of such articles for copyright information or permissions to reproduce.

Questions to ask:	What are the implications?
Are sources documented with footnotes or links? Where did the author get the information? As in published scholarly/academic journals and books, you should expect documentation. If there are links to other pages as sources, are they to reliable sources? Do the links work?	In scholarly/research work, the credibility of most writings is proven through footnote documentation or other means of revealing the sources of information. Saying what you believe without documentation is not much better than just expressing an opinion or a point of view. What credibility does your research need? An exception can be journalism from highly reputable newspapers. But these are not scholarly. Check with your instructor before using this type of material. Links that don't work, or that lead to other weak or fringe pages, do not help strengthen the credibility of your research.
If reproduced information (from another source), is it complete, not altered, not fake or forged? Is it retyped? If so, it could easily be altered. Is it reproduced from another publication? Are permissions to reproduce and copyright information provided? Is there a reason there are not links to the original source if it is online (instead of reproducing it)?	You may have to find the original to be sure a copy of something is not altered and is complete. Look at the URL: is it from the original source? If you find a legitimate article from a reputable journal or other publication, it should be accompanied by the copyright statement and/or permission to reprint. If it is not, be suspicious. Try to find the source. If the URL of the document is not to the original source, it is likely that it is illegally reproduced, and the text could be altered, even with the copyright information present.
Are there links to other resources on the topic? Are the links well chosen, well organized, and/or evaluated/annotated? Do the links work? Do the links represent other viewpoints? Do the links (or absence of other viewpoints) indicate a bias?	Many well developed pages offer links to other pages on the same topic that they consider worthwhile. Pages that offer opposing viewpoints as well as their own are more likely to be balanced and unbiased than pages that offer only one view. Anything not said that would be said if all points of view were represented? Always look for bias in text and links, especially when you agree with what's being said.

4. What do others say?

Techniques for Web Evaluation :

1. Find out what other web pages link to this page.

a. Use alexa.com:

Type or paste the URL into alexa.com's search box.

Click on the "Get details" button.

You will see, depending on the volume of traffic to the page:

• Traffic details.
• Contact/ownership info for the domain name.
• "Related links" to other sites visited by people who visited the page.
• Sites linking in to the page.
• A link to the "Wayback Machine," an archive showing what the page looked like in the past.

b. Do a link: search in Google, Yahoo!, or another search engine where this can be done:

1. Copy the URL of the page you are investigating (Ctrl+C in Windows).

2. Go to the search engine site, and type link: in the search box.

3. Paste the URL into the search box immediately following link: (no space after the colon).

The pages listed all contain one or more links to the page you are looking for.

If you find no links, try a shorter portion of the URL, stopping after each /.
Note: Different search engines give very different results for "link:" searches. We suggest trying more than one.

2. Look up the title or publisher of the page in a reputable directory that evaluates its contents (ipl2, Infomine, About.com, or a specialized directory you trust).

3. Look up the author's name in Google or Yahoo!

For the most complete results in Google, search the name three ways:

a. without quotes:  Firstname Lastname

b. enclosed in quotes as a phrase:  "Firstname Lastname"

c. enclosed in quotes with * between the first and last name:  "Firstname * Lastname" (The * can stand for any middle initial or name in Google only).

Questions to ask:	What are the implications?
Who links to the page? Are there many links? What kinds of sites link to it? What do they say?	Sometimes a page is linked to only by other parts of its own site (not much of a recommendation). Sometimes a page is linked to by both its fans and its detractors. Read both points of view.
Is the page listed in one or more reputable directories or pages?	Good directories include a tiny fraction of the web, and inclusion in a directory is therefore noteworthy. But read what the directory says! It may not be 100% positive.
What do others say about the author or responsible authoring body?	"Googling" someone can be revealing. Be sure to consider the source. If the viewpoint is radical or controversial, expect to find detractors. Also see which blogs refer to the site, and what they say about it. Google Blog Search is a good way to do this; search on the site's name, author, or URL.

5. Does it all add up?

Techniques for Web Evaluation :

1. Step back and think about all you have learned about the page. Listen to your gut reaction. Think about why the page was created, the intentions of its author(s).

If you have doubts, ask your instructor or come to one of the library reference desks and ask for advice.

2. Be sensitive to the possibility that you are the victim of irony, spoof, fraud, or other falsehood.

3. Ask yourself if the web is truly the best place to find resources for the research you are doing.

Questions to ask:	So what? What are the implications?
Why was the page put on the web? Inform, give facts, give data? Explain, persuade? Sell, entice? Share? Disclose?	These are some of the reasons to think of. The web is a public place, open to all. You need to be aware of the entire range of human possibilities of intentions behind web pages.
Might it be ironic? Satire or parody? Think about the "tone" of the page. Humorous? Parody? Exaggerated? Overblown arguments? Outrageous photographs or juxtaposition of unlikely images? Arguing a viewpoint with examples that suggest that what is argued is ultimately not possible.	It is easy to be fooled, and this can make you look foolish in turn.
Is this as credible and useful as the resources (books, journal articles, etc.) available in print or online through the library? Are you being completely fair? Too harsh? Totally objective? Requiring the same degree of "proof" you would from a print publication? Is the site good for some things and not for others? Are your hopes biasing your interpretation?	What is your requirement (or your instructor's requirement) for the quality of reliability of your information? In general, published information is considered more reliable than what is on the web. But many, many reputable agencies and publishers make great stuff available by "publishing" it on the web. This applies to most governments, most institutions and societies, many publishing houses and news sources. But take the time to check it out.

WHY?  Rationale for Evaluating What You Find on the Web

The World Wide Web can be a great place to accomplish research on many topics. But putting documents or pages on the web is easy, cheap or free, unregulated, and unmonitored (at least in the USA). There is a famous Steiner cartoon published in the New Yorker (July 5, 1993) with two dogs sitting before a terminal looking at a computer screen; one says to the other "On the Internet, nobody knows you're a dog." The great wealth that the Internet has brought to so much of society is the ability for people to express themselves, find one another, exchange ideas, discover possible peers worldwide they never would have otherwise met, and, through hypertext links in web pages, suggest so many other people's ideas and personalities to anyone who comes and clicks. There are some real "dogs" out there, but there's also great treasure.

Therein lies the rationale for evaluating carefully whatever you find on the Web. The burden is on you - the reader - to establish the validity, authorship, timeliness, and integrity of what you find. Documents can easily be copied and falsified or copied with omissions and errors -- intentional or accidental. In the general World Wide Web there are no editors (unlike most print publications) to proofread and "send it back" or "reject it" until it meets the standards of a publishing house's reputation. Most pages found in general search engines for the web are self-published or published by businesses small and large with motives to get you to buy something or believe a point of view. Even within university and library web sites, there can be many pages that the institution does not try to oversee. The web needs to be free like that!! And you, if you want to use it for serious research, need to cultivate the habit of healthy skepticism, of questioning everything you find with critical thinking.
