In the first number of Radiography Open, the article-Knowledge management: How to find the best knowledge sources was published (Nordsteien, 2014). Several free access research databases and resources were presented relating to evidence-based practice (Nortvedt et al., 2012) and the knowledge pyramid of Dicenso, Bayley and Haynes (2009). It is often possible to find a specific article by searching for the title in Google. To find any article on a topic, you will probably succeed by entering the subject in the search field of research databases. However, if the aim is to find all or the best information about a topic, you have to use advanced search techniques. Illustrating how to do a systematic literature search is the aim of this second brief article on knowledge management.
