In Google Scholar, click on the three bar icon and then select Advanced Search:
Coverage: Google Scholar indexes papers, not journals, that are available on the web. The best way to check current coverage of a specific journal in Google Scholar is to search for a sample of their article titles in quotes.
Searching: Google Scholar is very similar to Google; you can use many of the same search options
Advanced Searching: To do an advanced search, select the three-bar icon (upper left hand corner) and then click Advanced search. You will then see options to search by title, author, journal, date range, etc.
Save, Cite, and Cited by options are also available. The Cited by link lists the number of times an item has been cited by others, and can help you find more recent articles on a topic and trace the evolution of an idea from an original source.
