Once you have created content, you will of course want to use it in other projects and documents if possible. The “traditional” method for this is copy & paste; however, you will need to maintain and manage all the copied content in its various locations if something changes. Instead, in a content management system, you simply create a link to the existing content in your new project and reuse it. This not only works with whole chapters, but also with individual paragraphs, sentences, elements within sentences, images, tables, and so forth.
There are several advantages to this approach. On the one hand, it simplifies management of the content, as if a text or image needs to be updated, you only need to edit the original node. The update is automatically applied to all places where a link to the original node has been created by reusing content. This also ensures that no relevant place is accidentally overlooked. On the other hand, reusing content results in greater consistency among the documents. This is why your readers also benefit from the resulting recognition effect.
