For many databases and websites, Zotero senses when a list of books or articles is displayed by showing an icon in the address bar. This citation information can be saved with just a few clicks.
Adding PDFs
To include a PDF or any other file from your computer in Zotero, simply drag it to Zotero — you can drag to an existing item to attach the file or drag between items to store as an independent item. Zotero will automatically retrieve bibliographic metadata for the PDFs.
