Comparative Checklist for Analyzing Print & Electronic Sources: What to Look for

Our historical era is sometimes referred to as the "Information Age." We live in a sea of data, bombarded on all sides by facts, statistics, technical definitions, stories, brochures, jokes, pictures, magazines, newspapers, radio, TV, films, books, ads, handouts--all of uneven quality. Of all this information, we can usually trust that which has been collected in a library, at least to some extent, because professional librarians have judged it worth the cost of acquiring and storing this information, which most often is printed on paper.

Internet information is different and more challenging. Some internet information is excellent. But much internet information is also worse than useless because it is deceptive. At first glance it may look authoritative, but further scrutiny reveals it as incomplete, commercially or otherwise biased, out-of-date, or just wrong. Or at first glance internet information may not itself look worthwhile, yet it may include links to other valuable data. How can you determine the value of a potential research source? Where exactly should you look in a source for features that determine its quality? What specific features of a source reveal its worth and allow you to evaluate its usefulness?

The following table is designed to help you evaluate research sources. It lists these specific features that you should examine. Match up each of your sources against the features in this list. Consider each feature and what it suggests about the value of the source being examined. Working through each feature will build an impression in your mind of the value of the source under examination.

Note: Not all these features are present in all sources.

"Print" source means a source that was originally published on paper, even if you are reading an emailed copy from an online database like Melvyl or an online news service.

"Electronic" source means a WWW page on the Internet.
