In our everyday lives it is very common for us to get answers to questions by consulting the Web. We can find almost anything there in just a few seconds: recipes, driving directions, gardening tips, weather forecasts, movie times, song lyrics, baseball scores...the list is almost endless. We've all become very efficient at "jumping online" to get answers and solve problems.
Researching within higher education is different. Research in the fields of nursing and allied health, in particular, requires the almost exclusive use of scholarly sources. There are a few exceptions.

Review articles (AKA filtered information: includes literature reviews, systematic reviews, meta-analyses):
Primary research articles (unfiltered information: research studies, reports, clinical reports):
Case studies (unfiltered information: includes case reports)
