Yahoo Site Explorer used to be able to extract backlinks for a specific page. Our backlink database will also be able to do that it a while, but for now the best way out would be to gather backlink to the whole domain, then update just the "Page info" ranking factor and, sorting by the "anvhor URL" column, leave only the backlinks you need in the workspace.

LinkAssistant, when will your database be able to do that?
If you have a site with thousands of backlinks it takes many hours to gather all the backlinks, even though you only need the backlinks for that specific page.
