difference between google scholar and pubmeddifference between google scholar and pubmed

Introduction Today the majority of scientific research is published in the form of journal articles which can generally be found in bibliographic databases. Although Google Scholar retrieved twice as many relevant articles as PubMed (in the first 40 citations), 80% of relevant articles were not retrieved by either source.

Haynes RB, Wilczynski NL. The evaluation of published indexes and abstract journals: criteria and possible procedures. Conclusions: PubMed searches and Google Scholar searches often identify different articles. Similar results were seen in our study when we considered all records that were retrieved and not just the first 40. Results from our survey indicated that 80% of nephrologists do not review beyond 40 search results, which is the equivalent of 2 default search pages in PubMed [28]. Literature searches are essential to evidence-based respiratory care. The search results were analyzed to determine possible reasons for the retrieval of unique items in each resource and to gather information on the general features of the Google Scholar results. While its advantages are substantial, Google Scholar is not without flaws.

The topics selected were loosely based on questions received during reference transactions or were previously developed for use during instruction. As a library, NLM provides access to scientific literature. Google Scholar performed well, in some cases retrieving citations that other search engines did not. To ensure that the clinical questions tested were relevant to practicing nephrologists, we gathered questions using renal systematic reviews that targeted questions in patient care where uncertainty exists. Falagas ME, Pitsouni EI, Malietzis GA, Pappas G. Comparison of PubMed, Scopus, Web of Science, and Google Scholar: strengths and weaknesses.
