leave the books.. its simple... check the column dates... if u need to confirm date of the columns u can search the Archives of Jang and Express... i can post u the columns along with the newspaper with dates writen on it
if u think that there is confusion in dates... u mean to say that Javaid Ch. rpeated a column on 14th august 2007 from his some old book././.. lolz u must b kidding dude
