Organizing your RefWorks library is easy. You can create as many folders as you want and put your citations in them as you choose.
To create a folder, pull down the Folders menu and select Create New Folder:
Once you create folders, you can begin putting citations in them. Begin by clicking the box next to citations to select those you want to move to a particular folder. Or you can choose the Select All by clicking on the References to use: PAGE radio button. Then, use the Put in folder... pulldown menu to send the selected citation(s) to a folder of your choice.
