Created by Andrew Booth from the ScHARR Library at the University of Sheffield, this searches over one hundred web sites associated with the methodology of evidence based practice (EBP). It is useful for finding information about the practice and teaching of EBP concepts.

• Tips for learning and teaching
  There are 2 versions of each article, one for learners of the EBM principle in question and one for their teachers. The learners' version appears in CMAJ and J Gen Intern Med, and the related teachers' version is published online. (Link to the teachers' version from "Online Appendix" of the learners' version.) The online teachers' version will also give readers access to a variety of extra features, including an interactive version of the teaching article.
