Wikisource:User access levels

Groups
Typically all advanced rights holders have also been members of the administrators group of the community, and confirmation for those roles take place at the same time.
 * Users (every account)
 * Autoconfirmed—automatic after 4 days, and 10 edits; can be reverted. Autoconfirmed rights are needed for editing some pages that had an increased protection level applied, typically due to persistent drive-by vandalism.
 * Autopatrolled—applied by administrators to users who display understanding of style guide and use of respective namespaces. The autopatrolled group confers no actual additional rights nor affects what you can do in any way. It is only a way for admins patrolling new edits to avoid having to see your edits in the feed once they are certain that your edits no longer need patrolling.
 * IP block exempt—applied upon request
 * Bots—by application and consensus of the community (see Bot policy)
 * Bot users—can be self-applied and removed by administrators; can otherwise by applied and removed by bureaucrats
 * Abuse filter editors–can be self-applied and removed by administrators; administrators can apply or remove to others with approval of community
 * Commons media local uploader—restricted right that allows new local uploads to an existing filename
 * Advanced rights
 * Administrators, and see Adminship—by consensus of community
 * Bureaucrats—appointed by consensus of the community
 * Interface administrators—appointed by consensus of community
 * Checkuser—currently zero, and see Checkuser policy; applied by stewards through request
 * Oversight—currently zero, and see Checkuser policy; applied by stewards through request
