The simplest way to add items to Zotero is to use a Web Browser Connector (install instructions).
When you find a source you would like to save, click on the connector button. You will see a pop-up indicating that Zotero is saving your citation.
If Zotero detects that you're looking at a book or article on a catalog, database, or site, you'll see a book or page icon appear in your browser's address bar. Just click the icon and Zotero will automatically save the citation.
