About permission settings for lists and libraries

Microsoft Windows SharePoint Services provides the ability to control permissions on a specific list. If you have sensitive information stored in a list, and you do not want to expose the information to all members of a site, you can specify permissions for the list to control which users can view, edit, or add items to that list. You can grant or revoke permissions to a list or document library by individual users, by groups of users, or by site group. You can apply specific permissions for any list or document library in a Web site based on Windows SharePoint Services.

Any users with the Manage Lists right can change list permissions. By default, the Administrator and Web Designer site groups include this right. Any user with Full Control permissions for that list can also change list permissions. By default, all members of a Web site have access to all lists and document libraries on a Web site. All users assigned to a site group are considered members, except for the Guest site group. By default, each site group has a predefined level of permissions for all lists and document libraries. The default list permissions are:

• View items (given to the Reader site group by default)
• View, insert, edit, delete items (given to the Contributor site group by default)
• View, insert, edit, delete items; change list settings (given to the Web Designer site group by default)
• View, insert, edit, delete items; change list settings; change list security

In addition, you can set advanced permissions, which allows you to grant any of the following rights for a user or site group:

• Manage lists (given to the Web Designer site group by default)
• Manage list permissions
• Cancel check-out (given to the Web Designer site group by default)
• Manage personal views (given to the Contributor site group by default)
• Add list items, edit list items, and delete list items (given to the Contributor site group by default)
• View list items (given to the Reader site group by default)

Important  Members of the Administrator site group always have the highest level of permissions for all lists and document libraries. You cannot change list or document library permissions for the Administrator site group. Also, any site group that has the View Lists Item right (such as Reader) can continue to see the list name, description, number of items, and time when the list was last modified, even though they cannot view the list contents directly.

To specify permissions for a list, go to the list itself or to the Customize List_name page for the list.
