I want to show some documents in the content library to customer community users. Can this be done?

    Update Customer Portal profiles:

    Clone the Customer Portal User or Customer Portal Manager profile.

    In the cloned profiles, add the “View Content in Portals” user permission.

    Change the tab visibility for the Libraries, Content, and Subscriptions tabs from Tab Hidden to Default On.

    Assign the cloned profiles to your Customer Portal users.

I cant find View Content in Portals for the foll licenses

Authenticated Website
High Volume Customer Portal
Customer Portal Managed Custom
Customer Portal Managed Standard

Is there some way we could enable content for these licenses?
