Searches by general
search engines, such as Google Scholar, may return results that are limited or that do not reach very far back into the records. For cursory results or beginnings this may be adaquate. Deep searches should be conducted on specialized databases, such as PubMed or CINAHL.
Because of the extreme difference in response levels, the data is shown in 3 categories to allow comparison. Otherwise, the enormous usage of the Databases link would flatten all of the other bars realtively. Red Bars (< 1,500) are relative to each other. Orange Bars (1,500 - 25,000) are relative to each other. Purple Bars (> 25,000) are relative to each other.
