Source Evaluation: CRAAP Test: C is for Currency

A quick reference guide to help you decide if a web resource is worth using.


Currency refers to when the information was posted or published. It is also important to look at the entire website's timeliness. If it has remained dormant for some time, it may be a warning.

Some Questions to Ask

  • When was the information gathered?
  • When was it posted or published?
  • When was it revisited or updated?
  • Is the site up to date?
    • Do the links work?
    • Are there other more recent updates?


How important is currency? That really depends on your topic and discipline. Sciences and medicine change rapidly and unless if you are doing a historical piece on those topics, you are going to want to most current information available. If you are working with history or literature, it's quite possible that the currency is not very important. Use your best judgment and don't be afraid to ask a librarian or your instructor.
