The purpose of this newsletter is to inform about the latest scientific studies concerning Google Scholar as a source and tool for scientific evaluation. Only studies with an empirical perspective, that is, those which yield quantitative results that can be contrasted, verified and compared in order to confirm their reliability and validity, will be discussed here. Works that contain opinions, personal considerations or discussions without the support of empirical evidence that demonstrates the utility and advantages (or lack thereof) of using Google Scholar as a source for scientific evaluation, will be excluded from this newsletter.

It is known that any news concerning a product released by Google in the field of scientific information and evaluation will undoubtedly get widespread coverage both from the media and the scientific community, sometimes even causing heated debates among the involved actors. Because of this, we understand that there is nothing better than to offer empirical evidence, based on scientific research, about what the best uses and applications may be for these products, determining precisely where their strengths and weaknesses lie as a source for the evaluation of scientific information.

This newsletter will have two sections:

  1. Bibliography: this section will contain a list of all empirical studies published to date, sorted by year of publication.
  2. News: this section will contain a summary of the main discoveries and conclusions from the empirical studies as they are published.
