Category systems are in essence the same as outlines. Categories allow you to group references, quotations and thoughts that are related in some way. A category system can also be used to bring systematic order to all of the titles you have added to your project.
Switch to the Knowledge Organizer.
Click Categories and then click the plus sign icon and select New category.
If you already have a document with an outline (for example, a Word document), you can import it and Citavi will create a category system from the document.
Hint: If you want to use your outline in Word, insert it using the Word Add In. This lets you use the features on the Chapters tab in the Word Add-In.
