Need to find same things but with different values

Hello,

I'm wondering how could I do this. For example, I have list of 150 countries with different index attached to each country and I have different Excel for years 2012/2010/2008/2006.

Now I only need data for only 20 of the countries, how can I do this quickly without doing all the "CTRL + F -> Selecting Data -> CTRL + C" manually?

Thank you!

Anyone can help?
