The CRAAP test is designed to help you evaluate the nature and value of the information that you find while doing research. Each letter stands for a different criterion that you should consider when determining whether or not to use or trust a resource.
When any kind of research is undertaken, the process begins with a careful, often critical and analytical, review of the work that has already been done that is relevant to the project at hand. Some of this earlier work will be incorporated into the current project, to support the researcher's basic approach and theories; some of it may be refuted by the research being done; all of it is important to understanding how the researcher's work fits into the field in which they are working.
Documentation is the careful way in which the researcher tells her/his readers which of these works he/she is using, and to what purpose. Without documentation, subsequent researchers will waste valuable time replicating work that has already been done, but not documented for others to find.
Many of the GALILEO databases include citation helper utilities. Similar tools are available free on the Internet. NO citation helper or documentation management tools -- even the expensive ones -- are 100% accurate. Use them as short-cuts, not as the last word. Always use the manual, or a guide to the manual, required for your assignment to verify that your details are correct.
