2. Finding the evidence

Once the question is compiled, one must seek relevant evidence that will help answer this question. 

Source of information include:

• Textbooks and journals (although often disorganized or out of date)
• Colleagues of experts in the field
• Secondary sources of reliable summarized evidence (Archimedes, Clinical Evidence, BestBets)
• Online electronic bibliographic databases (Cochrane Library databases, MEDLINE, EMBASE, CINAHL) 

Remember to generate appropriate keywords for your searches and to use the Boolean operators "AND" and/or "OR" to combine or refine searches.
