There are two ways to gather citations in Library Search: formatted and by downloading an RIS file.
Formatted Citation
To gather a formatted citation, select a reference after running a search in Library Search. Then, scroll down and select the double quote icon marked "Citation" under "Send to" to view the citation and to select your preferred format. Then click on "copy citation to clipboard" and paste the formatted citation into your document.
RIS File
There are two places to download an RIS file, from the main search page and from a reference's page.
Downloading an RIS file from the main search page allows you to download references in bulk. First, select your references by clicking the checkbox next to the reference entry. Then, click the three dots next to the pushpin icon on the right-hand side of the screen below the search bar. Finally, click Zotero/RIS and download to download your references.
To download an RIS file from a reference's page, scroll down to send to and select Zotero/RIS file. Without changing the drop-down option, click download.
For more information on Zotero and other citation managers, see the Citation Resources: Reference Management Software guide.
