submit site to several suitable directories

When I searched for a site in dmoz, several items in different directories appeared. Is that means that a site can be placed in several directories? Therefore, I want to submit my site to several directories that are suitable concurrently. Can I do so?

Harry, I think my response to someone else answers your question. See:

If that doesn't answer it, post here again.
