Establishing Credibility

Check for Previous Work: Do two separate sources confirm the original report? Are the sources unbiased and independent?

Go Upstream: Find the source of the original report (statistics, journal, government site, newspaper). Is it reputable?

Read Laterally: Read other reports of the same story. Are they from different sources? Do they confirm or conflict with original report?

Circle Back: Go back to check for previous work when the source is not trustworthy, or a presented statement or fact has become complex, or there are multiple sub-claims. Try a new search of different fact checking sites or find alternate sources.

Articles from 1923 through 1998 are not available digitally--you would need to use microfilm. Microfilm is an old but stable technology used to preserve printed materials. At Wayne State University, you can use microfilm readers in the Purdy/Kresge library to read and save (to PDF) materials that are available on microfilm.
