Weekly Rankings Archive?

I was wondering if there is a site that contains the rankings from every week of the WTA Tour since 2003-2004 to the present? I am working on a school project and would really appreciate any help

So have the points from last year's Rome tournament been taken off or do they come off next Monday?
