# Lost on an Integral

I have an integral I want to work out that should be a simple one but I just can't see where to start with it. Any help would be appreciated.

$$\int\frac{lnx}{x-8xln^2x}$$

Write it as:
$$\frac{1}{2}\int\frac{2\ln(x)}{x}\frac{dx}{1-8\ln^{2}(x)}$$

i haven't done it but it looks like trig substitution might work

Substituting for ln^2(x) works even better..
