Have the book in front of you and want to add it to your Zotero library without having to search for a citation?
If you have a book's ISBN, an online article's DOI or PMID number, just click the magic wand button: "Add item by identifier." Type in the book or article's number, and Zotero will automatically download its information and save it to your library.
To archive a web page, click the “Create New Item from Current Page” icon (). This will create a web page item in your library with basic information from the page.
If “Automatically take snapshots when creating items from web pages” is enabled in the General pane of the Zotero preferences, a copy of the web page will be added as a child item. To see the page as it was on the day you captured it, double-click the snapshot icon, as shown below.
