Google's "link:" operator has only returned a "sample" of your inbound links for at least three years now. It is absolutely not
at all a reliable indicator of your inbound links or of the links that Google "counts" in your favor.
Go to Google Webmaster Central
and sign up for Webmaster Tools. Register and validate your site with Webmaster Tools, and you can check your links there, as well. (Note: this is the service that used to be known as Google Sitemaps. While you can use also use the service to submit a sitemap, it is not necessary to create or use the sitemap feature in order to make use of the rest of the information. I highly recommend the Webmaster Tools as an informational resource for all site owners.)
The list you will find there is not necessarily a complete list of the links pointing to your pages which Google knows about, but it does appear to be more complete than the selection you'll get by using the "link:" command.
