Each book has a built-in glossary, but to access it, you will need to create a chapter, give it a short name of glossary, and while editing the chapter selecting the Special Include called "Glossary of Terms."
Once you save the chapter, you will have access to add and edit glossary terms for the book. Note that only book editors (not chapter editors) have access to edit glossary terms. However, chapter authors can access glossary term in lists within their chapters (as explained below).
While on your glossary page, you can add new terms using the form at the bottom of the page. Each glossary term requires a name, anchor name, and description as follows:
For any term that is created, click the pencil icon next to it in order to edit.
You can include an automatically updated list of glossary terms with definitions in any chapter. This is useful if you would like to include a list of key terms within a chapter that will be updated as glossary definitions change.An example of an automatically-created list of glossary definitions to be included in a chapter
To do this, edit the chapter, place the cursor where you would like the list placed, and select Tools > Glossary Terms List.
In the Anchors field, type in a comma-separated list of anchors for the book's glossary terms that you would like to have listed, and click Submit.
When saved, the chapter will display each glossary term with its definition. It will also link the terms to your manually-created page with the short name of glossary.
If you would like to edit the included list later, you can change the terms, delete them, or add new ones directly in the editor.
To update the text that appears in the chapter as glossary terms are changed, simply edit and save the chapter again.
