Scratchpads can keep track of the changes made to a node of a content type. These changes are stored as different versions of the node called revisions. Revisions can be very useful when data are updated by different authors.

Enabling Revisions for content types

  1. From the Admin bar go to Structure > Content types
  2. Click Edit next to the content type you wish to enable or disable revisions for
  3. Click on Publishing options and select Create new revision
  4. Click Save Content type

If Create new revision is specified for a content type, every edit will, by default, create a new version of the page.

This can be overridden in the Revision information on a node - along with setting a more informative revision log message.

Comparing Revisions

Once you have created a new revision of a node in the content type you can compare their differences:

  1. Locate and view the node you wish to see the revisions for.

  2. Click on Revisions tab

  3. Select the revisions you wish to compare and click Compare


Note: If a field accepts HTML input, it might be easiest to view changed without HTML tags - to remove the HTML tags click on Marked down
