Of literature review

"Leedy and Ormrod (2005) noted that one common rule of thumb is that the search is near comple-tion when one discovers that new articles only introduce familiar arguments, methodologies, findings, authors, and studies. Thus, when reading a new literature piece, if one “will get the feeling that ‘I’ve seen this (or something similar to it)before’” (Leedy & Ormrod, 2005, p. 82), it may suggest that the literature search is near completion. The end of the search can also be indicated when no new citations are discovered and articles cited in newly discovered literature have already been reviewed. In sum, as Webster and Watson (2002) observed: “You can gauge that your review is nearing completion when you are not finding new concepts in your article set” (p. 16)"
