Zotero organizes your research into collections that act like iTunes playlists. You can add a citation to any number of collections or subcollections. Create a new collection by clicking the folder icon above the library pane.
You can drag and drop citations onto the new collection. With the collection selected, any items you save will automatically be filed into the collection.
You can search the citations and fulltext for anything in your Zotero Library. From the search dropdown, select.
With saved searches, you can create smart collections that automatically fill with relevant materials as you add them to your library.
Click the magnifying glass to use the Advanced Search. Enter your search terms and click.
