Frequently Asked Questions
How do I access Google Scholar Advanced Search?
Click the three-line menu icon in the top-left corner of the Google Scholar homepage and select “Advanced search.” This menu allows you to limit results by specific authors, journals, dates, or precise phrases.
Is Google Scholar better than PubMed or Scopus?
It depends on your goal. Google Scholar offers a far larger, multidisciplinary index and is completely free. However, databases like PubMed offer highly specialised filtering for medical literature, and Scopus provides stricter quality control.
Can Google Scholar export to Zotero and EndNote?
Every search result includes a “Cite” button. Clicking this allows you to download citation files formatted directly for reference management tools such as Zotero, EndNote, Mendeley, and RefWorks.
What are Google Scholar metrics like the h-index and i10-index?
These are tracking metrics displayed on public author profiles. The h-index reflects the number of papers (h) that have received at least h citations. The i10-index tracks how many academic articles an author has published that have received at least ten citations.
How do I set up citation alerts in Google Scholar?
Log into your account, perform your keyword or author search, and click the “Create alert” envelope icon located in the left sidebar. Google Scholar will automatically email you whenever a new document matching your search rules is indexed.
