Document version discoverability and persistence are provided. A version history of a document includes snapshots of the document as it is created and edited over time. When a version history for a document is invoked, a list of the previous versions of the document is generated for display. Certain versions may be more important to a user. Upon selection of a version, an option to append identification metadata to the selected version is displayed. Received text input is appended to the version of interest, and stored as identification metadata. When a user subsequently selects to view the version history of the document, the identification metadata are displayed with the version of interest, enabling the user to quickly and easily identify the version of interest. Additionally, the version of interest is prioritized, ensuring that it is persisted and not purged when older versions are removed from storage.
