RefWorks recently announced the availability of new Write-N-Cite utilities for RefWorks users. These new versions are available from their Write-N-Cite Download page. From the press release:
We are pleased to announce that Write-N-Cite III for Windows has completed beta testing, and the final release version is now available. This optional plug-in allows for single document formatting (and unformatting), as well as the ability to write and format a paper completely off-line, allowing users to be more mobile and efficient. For Mac users, Write-N-Cite v2.5 for Mac is also now available. This latest version works with Microsoft Word 2008 and the Leopard operating system and provides the same features as the current Write-N-Cite for Mac.
