New information and discoveries can quickly make books or articles outdated. Depending on my topic, my information may need to be only a few years old or maybe even a few months old.

Ask yourself these questions:
  • When was the information published or posted?
  • Has the information been revised or updated?
  • Does my topic require current information, or will older sources work well?

Let's see how this works. Look at the citations for articles below.
