Where can I get the pre-European records of the day to day living among the Annangs in Nigeria?

Question

This should include sites where I can have free downloads of such pre-European studies of the Annang people - religion, sociology and wars

Answer 1

Can't give you a specific site; other than your school or public library (failing that, the local university might do).

The problem with pre-European records is that there often aren't any.  Even before the Europeans started sailing out and exploring Africa after the Renaissance, Europeans still visited large parts of Africa, btw.

Your best bet is archaeologists who study that area, but since many of the tribes are nomadic, it is difficult at best to find out information on them.  

And if this is for school; be warned that for every good idea on the internet, there are likely a billion foolish, wrong or just plain stupid ones; so caveat emptor!
