# Tags

Tags enable comprehensive categorization of a bookmark, permitting classification based on their subjects, approaches, statuses, evaluations, or even your personal workflow (such as 'to-read').

You can add up to 10 tags per bookmark, and you can refine your library or a particular collection by displaying items associated with a particular set of one or more tags.
