RefWorks Citation Manager (RCM) is a tool you can use within Word to add references directly to your work and then generate a reference list/bibliography based on these in-text references. RCM is available via the Store in Word (once installed it should appear within the ribbon).
If you have Word 2016 or above on your device, you would ideally use RefWorks Citation Manager (RCM) rather than Write-n-Cite (WNC) to insert citations and bibliographies into your documents.
Please note: if you have already started a document using Write-n-Cite you must finish it using that tool as you cannot switch between RCM and WNC within a document.
The latest version of RCM was released in May 2020; if you have previously installed RCM it may automatically upgrade. If it doesn't upgrade you can uninstall it and re-install it - however, if you are still working on documents, do not manually upgrade until you have finished all current documents.
