Bookem allows you to view previous versions of a document so you can track changes over time and see who worked on a document and when edits were made, which can be particularly useful from a medico-legal perspective.
Follow these steps:
Open the document you want to review as you normally would
Scroll to the bottom of the document and click the ∧ icon to expand the footer
Click 'View version history' to open the full version history panel
The version history panel opens on the right-hand side, with the current version indicated at the top of the document
Click on any listed version to view its contents
Select the version you'd like to restore in the version history panel
Click 'Restore this version' to replace your current content with the selected version
Remember to click 'Make a copy' to preserve the current version if necessary
When you're ready, click 'Restore' to restore the selected version
