If you're using Internet Explorer or a mobile browser, you can still save items to your Zotero library. A free Zotero account is required.
The Zotero Bookmarklet works with all desktop browsers and most mobile browsers (including Safari for iPad and the Android browser).
Visit the Zotero Bookmarklet page for installation instructions for your particular browser or device. You won't have to install any software -- just the bookmarklet!
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.
Juris-M is a variant of Zotero, with legal and multilingual support. Most importantly it provides modular support for legal referencing and legal students can download citation styles fitting their special needs.
