sequences and series - sumngeq1frac(1)nlnnn

How can we compute the series n1(1)nlnnn?



I know it is η(1) , where η is the η Dirichlet Function , i know its value. But I don't know how to compute it.



An approach I tried is to expand the series, then gather together the odd and the even terms , use ζ (Riemann's function) and that's all. Then no idea.



Any ideas are welcome.
