# Metadata History: Comparing change logs
In the Aristotle metadata registry, we can view and compare the change logs for each metadata item. The history/compare feature enables us to track these change logs with additional details, such as the user who made a change and the specific modifications made.
Follow the steps below to view the history of a metadata item and compare the change logs:
1. Navigate to the metadata item page you want to see or compare change logs for. For instance, I am on the 'Northwind Dataset' item page. On the item page, click on the 'History' tab.
2. You will see a list of all the changes to the metadata item page here, with additional details like Date/time, User, Comments, and visibility settings. Select the two change logs that you want to compare and click on the compare button.
3. On this page, you will see highlighted text in red and green. The green color indicates what has been added, while the red color indicates what has been removed or deleted in the selected change logs.
That's how we can keep track of and compare the change logs for any metadata item.
