in google webmaster tool there is option to submit sitemap in text format...a text file with nothing just link line by line.....you can paste all your article link in the text file and submit to google..if there is a new article update the text file then resubmit...if i'm not mistaken, the submitted text file can have more than 1000 links...this is tiresome..not recommended...hehe
