Migrating from RefWorks to Zotero can be done in just a few short steps. You will need the following (see the Step 1: Installation and account tab):
You can export your entire RefWorks collection as a whole, or you can migrate it one folder at a time. Please note that the process will not transfer any files that you have uploaded to your RefWorks account.
Navigate to the RefWorks folder you wish to export or select all your references. Once you are in the folder you wish to export, mouse over the References link in the toolbar and click Export.
Select All in List after References to Include..., and select Bibliographic Software (EndNote,Reference Manager,ProCite) from the Select an Export Format drop-down. Click Export References.
A new tab or window should open with text formatted like the below illustration.
Click the folder icon in the browser toolbar (circled in red in the above illustration). A pop-up will open. Click Select All and then OK.
Your items should now be imported into Zotero! Double Check your Zotero library to make sure they transferred.
If you are importing more than one folder into Zotero from Refworks, follow steps 1 - 3 again with each folder you wish to import.
