After publishing a catalog, it is common for users to make a copy of the catalog to begin editing a future version. In Coursedog this is referred to as "cloning" and it can be done in the "catalogs" tab under settings:
To clone a catalog, click the "CLONE" button under the "ACTIONS" section. This will pop up a modal in which you will name the new catalog.
You can think of a catalog as a set of custom pages, and cloning a catalog simply creates an identical copy of this set of pages. Each catalog is also assigned a top navigation and a side navigation, each of which is assigned to a "catalog scope" which determines the set of pages that the navigation is linking to. For this reason it is very important to ensure that each catalog has navigations that are assigned to the catalog's scope.
For this reason, when cloning a catalog, you should also clone the navigations associated with it. This is done in the "navigations" tab:
To clone a navigation list, click the "CLONE" button at the right of the screen, give the new navigation a name, and specify the "catalog scope" for the navigation.
