The decalogue of research questions is shown below:ġ. We will also try to answer some additional questions that hopefully shed some light about the use of GS as a tool for assessing scientific impact through citations. The objective of this work is to identify the set of highly cited documents in Google Scholar and define their core characteristics: their languages, their file format, or how many of them can be accessed free of charge.
Abstract: The study of highly cited documents on Google Scholar (GS) has never been addressed to date in a comprehensive manner.
