What is K-Pop?

Hey guys~

I have to do this project for school for two years. TWO FREAKIN YEARS.

But I was glad we could choose the topic. Gues what mine is~

Yep. It's about K-Pop...

But the problem is that we have to use books and not only the Internet.

And when we use the internet then it have to be sites that are.. uhm..  don't even know how to say this.. uh. scholarly..(?)
you know.. the language alone says that it wrote someone who really has a plan. 


Okay.. so .. I hope you know what I mean... xD
But now to the point: I have/had holidays and I still have more than a year to finish this work.. but since someone.. -cough- motivated me somehow..
I decided to do more than the teachers want from me right now and just finish my project earlier.. so that I have more time for a correction or for improvements in the end.^^

So.. My first Topic I have to work at is the question: "What is K-Pop?" 
So a definition, some history maybe and stuff like that..


And I wanted to ask if someone knows any sites or anything else(except for wikipedia) where I can get these information..
