Evaluating sources

Checklist for sources: the CRAPMAP

The CRAPMAP consists of a list of questions that help you to assess whether the (online) information you have found is reliable and useful. Depending on your situation, items from the list are more or less important. NB! Always stay alert! This checklist is just a tool and not always sufficient.

 Has the information been revised or updated? Or perhaps even retracted?
 Does your topic require current information, or will older sources work as well?

Relevance
