Google Scholar has a feature called My Library which allows you to save articles from the results page, organize and label them, and search the full text within the library itself. Within the My Library feature, you can edit the citation information and export them to a citation management software like EndNote. This is a great feature to utilize if you plan on using Google Scholar often as it allows you to keep up-to-date with important research topics and can be accessed any time you're online.
To get started, sign in to your Google Scholar account (or create one, if you haven't yet). Look for the My Library link after selecting the hamburger button at the top of the page. After enabling My Library, conduct a search and look for a Save button just below the citation. This will save the resource(s) to My Library.
In the My Library feature, you can add labels to your saved articles. To do this, navigate to My Library. Look for the Manage Labels option under the "All articles" column. You can create labels for specific topics, classes, group projects, and more. To create a label for an article, look for the Label option under the citation. An Edit Labels box will appear, allowing you to create a new label.
The My Library feature allows you to conduct a full-text search of the articles you've saved. To do this, look for the search box at the top of your screen and enter your search terms. If you want to search the entirety of Google Scholar and not just your library, select Articles from the hamburger button in the upper-left side of the screen.
