# Reuse of Textbooks

In Wikiwijs you can reuse a copy of a published arrangement. The different ways are described in chapter 'Copying'.
You then get a derivative arrangement. The arrangement that formed the source for your copy is the source arrangement.

You can disconnect the source arrangement from the derivative arrangement and adjust the arrangement to your own needs.

You can also choose to preserve the relationship between the derived arrangement and the source arrangement. If the source arrangement is updated by the creator, your arrangement will change immediately (if you wish).

Working with a derivative arrangement

- Copy the arrangement from Wikiwijs Search to your own Wikiwijs Maken environment. When you open a published copy in Wikiwijs Maken, you will see the name of the source arrangement on the 'Reuse' tab under 'Source arrangement'.

- Go to Content. If you do this for the first time, you will be asked if you want to keep the link with the source arrangement.

- If you click on 'No', the connection to the source arrangement will be disconnected.
  If you click on 'Yes', the connection will remain. Changes made to the source arrangement are automatically reflected in the derived arrangement.

When you want to change an element that is linked, you will first receive a warning that the link with the original will be broken. If you accept that, it is possible to adjust the element. This specific element is therefore no longer automatically adjusted when the source arrangement is changed.

If the base is changed for a decoupled element, this becomes visible in the derived arrangement. You still have the choice to make the change or ignore it.

NB1: you can also undo the pairing/unlinking choice for each element.

NB2: only existing elements are linked. Elements that are added to the source arrangement later do not appear spontaneously in the derived arrangement.
