If you've found (or work for) a directory we don't list, we'd love to add it.
It must be free (not a time-limited trial), show actual phone numbers for free, available to all internet users in all countries, reasonably complete, and ideally offer something (such as extra coverage) that isn't available on any directory already listed.
The directory can be in any language, but if it's in a language other than a major western European language we'd really appreciate some basic details of what it covers and how to use it.
If we consider it's a useful extra link we'll review it and add it.
