The Zotero developers announced that Zotero is now compatible with all PLoS journals. The new Zotero translator allows users to capture metadata and full-text PDFs of PLoS articles. I've tried Zotero with PLoS ONE and PLoS NTD articles and it automatically gathers metadata information including the authors of an article, abstract, volume/issue and DOI. You'll need to download the latest Zotero 1.0.1 release to get the new PLoS translator.

There's probably a fair bit of people scratching their head and asking "What is Zotero?" Zotero is a great Firefox extension that allows you to collect, manage and cite your research sources. It works seamlessly in your browser and automatically collects metadata from an article, allows you to create tags about the information and take notes. Best of all - it's free!

The developers have created a huge number of translators for libraries and universities around the world as well as translators for Amazon and Flickr. Zotero also has integration with Microsoft Word and OpenOffice so you can easily cite something from your Zotero collection. On of the Zotero team members is also working on a PLoS bibliographic style export which should be released in the next version.

Zotero is a great application and I highly recommended giving it a try.
