I know two other comparison of electronic site:seekic.com chinaicmart.com.
alibaba.com/ is good,but there are also useful for other B2B. Eg: ttnet.net , globalsources.com , ec21.com , ecplaza.net , made-in-china.com/ , importers.com , go4worldbusiness.com , hc360.com , alibaba.com/0 , alibaba.com/1 , http://www.trade-india.net/ , http://www.diytrade.com/ . These sites are also good sites.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
