Many thanks in advance.
Google's link: operator will never show you all your backlinks - it only ever shows a small sampling, and it is only updated every month or two. For more information about the link: operator on Google, see this thread: The link: Operator - it's not like other search engines! [webmasterworld.com].
For future reference, you can find this thread in the "Hot Topics" area which is pinned to the top of the Google Search forum's index page. There's lots of other good information in there, too. If you're completely new to SEO, you will probably need a lot of what's covered in there sooner or later.
