Currency

  • Currency is especially important in the sciences and social sciences where new studies appear frequently. In the arts and humanities, currency needs to be judged as appropriate to the research. A study written years ago may be essential for your research. Consider whether or not the timeliness of the information will affect its usefulness. 
  • If research results are given, consider not only the date of the publication but also when the research was actually conducted. 
  • For information found on the web there should be some indication of the date of the material. Be aware that the "Last updated" date of the web page may differ from date of the intellectual content of the page. This may mean checking three dates, the date the page was last updated or posted to the web, the date of publication, and the date of the research or statistics used.
  • Do the links work? This is an indication that the page is being monitored and adjustments being made.
