There are a couple of ways to quickly find popular (widely cited) articles on a topic or by a specific author.
One way is to use the Web of Science database available through Harvard Library. Use the search bar to search by topic or author. If searching by author, be sure to type the name as "Last name, First name" and select Author from the drop down menu. On the next page, you'll see a list of search results. At the top of the page you can toggle your search according to Times Cited and a few other categories. Click Times Cited to sort your results from most-cited to least cited.
You can see the number of times an article has been cited by looking at the right-hand column of your results.
Another way to quickly find widely cited articles is to use Google Scholar. On the left-hand side of the search page, click the three grey bars to expand a menu of options. One of the options is to do an advanced search.
In the advanced search you can enter your search terms or author name. Although there is no way to sort your results by number of citations, Google Scholar automatically sorts them this way if your search yields fewer than 1000 results. The number of citations appears just under the search result.
Make sure you have linked your Google Scholar account with Harvard Library to access full-text articles. Here is our FAQ on how to link your Google Scholar account to Harvard Library.
