Why evaluate sources?

Why evaluate sources?

Just because it’s written doesn’t mean it’s good…

Evaluating InformationToday, anyone who has the necessary skills can find a wealth of information on almost any topic.

Evaluating Information

The challenge is to sift through a huge amount of information and identify sources that are..

reliable and appropriate.

Evaluating Information

Whether you find information in books, magazines, on the Internet, or on TV, you cannot assume it is reliable.

Evaluating InformationThe researcher is responsible for evaluating information and judging its quality.

Evaluating InformationUse the following points to consider when evaluating any information source.

WEBSITE ADDRESS

Point #1:

Website AddressLook at the website address first – the

address can tell you lots about the source

www.urasucker4buying-this.com

www.rip-u-off.com

www.hot-n-naked.com

Website AddressLook at the address!

.edu = college/university.gov = U.S. government site.com = commercial site.org = Organization/group.mil = a U.S. military site.net = a network of computers.k12.us = public school

Website Address

The best sites for reliable information are:

◦.edu◦.gov◦.mil

Website AddressLook at the address!

.edu = college/university.gov = U.S. government site.com = commercial site.org = Organization/group.mil = a U.S. military site.net = a network of computers

Website Address: .edu.edu = Educational (university)

sites. We’d like to think these are among the most reliable of sites. ◦But individual (and sometimes strange)

students and professors can have their own personal pages under this domain, so you should still check the facts to ensure accuracy.

Point #2: Author

Author - No Name?

Websites are not always created by experts!

Author - No Name?

If you cannot find anyone’s NAME on the website, that’s a big RED FLAG

Author - No Name?

Sometimes questionable internet sources do not give the identity or credentials of the author or producer.

Author - No Name?

If you have a source with NO NAME or CORRESPONDING ORGANIZATION, do not use that source!

No way am I putting my name on THAT!!

AuthorIdentify the author(s)

A PERSONAn ORGANIZATION

Author A PERSON

A PERSON◦What are his/her credentials?◦Does he/she have sufficient expertise

to speak on the subject?◦Author's occupation / position?◦Author’s education? ◦Author’s affiliation with a known

institution or organization?

Author:An ORGANIZATION

An ORGANIZATION ◦Who are the leaders? ◦What is the mission of the organization?◦Is it a national or international

institution?◦What is its membership?◦Is it endorsed by or affiliated with other

organizations?◦Does it have a “parent” organization?

Author An ORGANIZATION

An ORGANIZATION ◦Check the organization's home page to

make sure it has a postal address and phone number available. If it does not, the site is probably not a credible source.

Look for any advertising on the site – ads can reveal what’s important to the organization

Look at the source to see if it tells you anything about the author's credentials. ◦“About us”◦“About the author”◦“Author Bio”◦“Mission Statement”◦“Who we are”

Author:How to Verify

Use a search engine (such as Google or Yahoo) to find information about the author(s) this is one good use for general search engines

Do a “Who is” search at www.whois.net to determine the website’s registered domain

Author:How to Verify

TIMELINESS

Point #3:

TimelinessWhen was the information

published?◦When was it last updated?

Is the date of publication important to the subject matter?

TimelinessHow can I find out?

Look at the date of publication or last update.

Determine whether it is important to use current sources for the subject.

TimelinessIn fields such as medicine, science,

business, technology, and most social sciences, currency of information is important.

(no older than 3 years!)

Timeliness

In fields such as history and literature, older materials may be just as valuable as newer ones.

So Cleo… what’s new with you?

Not too much Will…

DOCUMENTATION

Point #4:

DocumentationAre the links relevant and appropriate

for the site? ◦Do the links point inward, outward,

or both?

Link Link

Link Link

Link

Link

Inward links Outward links

DocumentationDoes the author refer to

other works?Does the source have a

works cited/bibliography?

DocumentationCan you find any cases where the

author has plagiarized other sources? ◦In other words, has the author used

words or ideas without properly citing them, so as to pass them off as original ideas?

DocumentationHow can I find out?

Does the author support his or her statements with data or references to research?

Look for a link to a bibliography or list of references.

DocumentationLots of info but NO SOURCES listed?

No sources… How can that be?

DocumentationNO SOURCES listed?

A legitimate site would not plagiarize. I usually look for another site that has sources listed.
