How do I attach a file or web page to an item?
After adding an item to your library, click on the Attachments tab in the right-hand section of the Zotero pane. A pull-down menu will allow you to add a link to a file stored elsewhere on your hard disk, copy a file to your Zotero storage directory, add a link to the current web page, or save a snapshot of the current web page.
