Zotero saves references from most library catalogs (including The Claremont Colleges Library Search) and databases, and even many regular web pages, with one click.
Zotero detects that you're looking at a book or article on a catalog, database, or a site like Amazon.com you'll see a book or page icon appear in or near the address bar of your browser. Just click the icon and Zotero will automatically save the citation. Zotero will import your citation into the last folder you had open.
Make sure Zotero is open before you begin to save citations, otherwise you will get an error message and the option to save it to your online account.
You can create folders to organize your citations. Citations can be present in more than one folder at a time.
You can also organize your citations using tags, notes, or the related function.
It's easy to attach files (like PDFs) to items in your Zotero library. Just drag the file into your Zotero pane. Dropping a file onto a collection, or in between library items, will copy it into your library as a standalone item.
Dropping it onto an existing item will attach it to that item. This is the easiest way to attach a copy of an article to its entry in your library.
