Findings may still be controversial. Gale Academic OneFile has a check box on the lower part of the search screen that lets you limit your results to scholarly journals.

They may be prepared by academic entities or by private consulting firms, sometimes under government contract. Technical reports state clearly the nature of the research or study and the methods used to collect and process the data.

Books written for a scholarly audience are held to higher standards than those written for the general public, and may approach scholarly journals in acceptability. Books cannot be as up-to-date as the most recent periodicals.

In the widely recognized magazines, an attempt is usually made to insure accuracy, but these publications are less carefully screened than scholarly journals. Some popular periodicals, such as Sierra, are published by organizations with a distinct point of view.

While a few nationally-recognized newspapers (for example New York Times, Wall Street Journal, and The Christian Science Monitor) have high standards and are equally acceptable with national news magazines, many local newspapers may contain inaccuracies and shoddy reporting.

Companies want to present information that will promote their business, and may be further restrained from total truth-telling by other considerations, for example, the fear of lawsuits. Check any facts you find on commercial sites in more neutral sources.

Some are more scrupulous about facts than others, but at the least you should expect that the information presented has been chosen with a conscious bias. It is best to seek independent confirmation of the statements asserted there.
