Checking in an item in SharePoint releases the exclusive lock on the item and allows other users, who have access, to view or edit the item. In this recipe, we will check in the publishing page we created in the Creating a publishing web part page recipe.

Navigate to the SharePoint list or library that contains the item to check in with your preferred web browser.
Select the item by clicking on the checkmark on the item.

Provide any applicable Check In notes.
Click on OK.
