Therefore, this tool would be of little use in an effective research activity. Furthermore, a recent study (Herrera,
2011) shows the importance of Google Scholar in terms of academic research.
Regarding the use of databases, we found that 40% of doctoral students have never used databases established by
the university, and 27% have never sought out foreign databases. Given this situation, the purpose of the university
library could be strengthened by providing training to new PhD students in the use of databases for literature
searches.
