It’s free, and possibly the most advanced web browser plugin I have seen so far. What it does? I have been using it for 20 minutes and already I could not do without: it manages my library references in such a brilliant way! I have been using several tools to manage my library and bibliographical references:
- Librarything: www.librarything.com/catalog/rvens This is currently the place most of my books are catalogued, and a fantastic social networking site for books.
- Bibliographix: www.bibliographix.com A tool I have been using for many years, runs only on Windows, but possibly the most extended bibliography manager there is.
- BiblioTalk: My own homegrown tool, doing things I could not do with the other stuff above.
Though I am using Zotero for only a very short time, I already think that some and maybe even all of the above tools may now be obsolete. The developers have done such a great job with this tool that is literally brimming with functionality, that my only reservation would be the fear that at some moment in time they will start charging money for it.
