Google Scholar is not enough to be used alone for systematic reviews

Google Scholar Could Be Used as a Stand-Alone Resource for Systematic Reviews

“…A majority of these studies conclude that although GS can be used as one of several bibliographic databases for literature retrieval, researchers should not use it as a stand-alone tool (Bramer, Giustini, Kramer, & Anderson, 2013;Giustini & Kamel Boulos, 2013). The authors of this study conclude otherwise, indicating that GS is sensitive enough to use as a stand-alone resource when performing systematic reviews.…”

“…However, it should also be kept in mind that there is only limited research available that has empirically determined the effect of any shortcuts or deviations from systematic review standards (Tsertsvadze et al, 2015). Only a few studies have investigated the incremental value of specific systematic review methods (Dickersin, Scherer, and Lefebvre, 1994;Moher et al, 2000;Bushman and Wells, 2001;Horsley, Dingwall, and Sampson, 2011;Giustini and Boulos, 2013;Selph, Ginsburg, and Chou, 2014;and Haddaway et al, 2015) or have tested the validity of the end product by comparing the conclusions reached in rapid reviews versus systematic reviews (Watt et al, 2008a;Watt et al, 2008b;and Hartling et al, 2015a). Hence, we know very little about the impact of deviating from full systematic review methodology.…”

“…Phase 3 used forward snowballing to find citations of the papers from Phase 1 and 12 papers were found. Giustini and Boulos (2013) found that Google Scholar alone was not enough to comprehensively conduct a SLR. For this reason we searched electronic databases (e.g.…”
