Reusable content and assets make updating your guides faster and simpler. When you update a reusable box/asset, the update is reflected in all instances, so you don't have to update each guide individually.
Staying current on LibGuides features and practices is also important, so that your guides continue to be accessible, current, and engaging.
If a guide is no longer relevant or was created for a class that is no longer taught, consider changing its status it to private.
A private guide is preferable to an unpublished guide because anyone with the guide URL will still have access to it. Unpublished guides are hidden from all users.
