Write-N-Cite is a plug-in utility that allows users to run an abbreviated version of RefWorks on their device; it allows the creation of citations while you are writing your paper. It is available for download from the ‘Tools’ option in the top toolbar after logging into RefWorks (available via the Library Database Page).
More information about Write-N-Cite, including installation and troubleshooting advice, is available from the Refworks FAQ site.
