1. If you are unable to automatically find the citation information for your sources when you drag and drop PDFs into your library, or if the "add to Zotero" icons are not available on the URL address bar, or if you just want to add the citation information for a print item that is sitting on your desk, first click the "New Item" icon on the Zotero toolbar to manually add items to your Zotero library. Second, choose the item type that matches your source.
2. You will be given blank fields in which to enter the information about your item (in the right-hand pane).
3. Click on the fields and/or use the tab key to navigate through the fields. Only add as much information as is needed to create a correct citation. Some fields are optional.
