Legacy RefWorks is retired from 30th June 2023 and will no longer be available.
If you used your legacy RefWorks account in the year up to 28th June and had not upgraded it, it may have been upgraded on your behalf. In this case you should have received an email from RefWorks about your new account.
See more information at 'Upgrading from Legacy to New RefWorks' and check the Writing Tools information - especially 'Upgrade a Write-N-Cite document' if you have active Word documents with in-text citations.
See more information about using the newer version of RefWorks.
