Identities For Generalized Harmonic Number I have been searching for identities involving generalized harmonic numbers
\begin{equation*}H_n^{(p)}=\sum_{k=1}^{n}\frac{1}{k^p}\end{equation*}
I found several identities in terms of $H_n^{(1)}$, but I am looking for some interesting identities for $H_n^{(2)}$. Does anyone know of any identities know of any nontrivial identities for $H_n^{(2)}$?  I found some listed on Wikipedia, but this list is not comprehensive. Thanks for your help.

*integral identities

*summation identities

*recursive identities

*in terms of another function


There is a nice list and a set of references at mathworld.  Additionally, I discovered this one while writing a thesis on the Riemann Zeta function.
$$\sum_{n=1}^\infty \frac{H_n^{(s)}}
 {n^s}=\frac{\zeta(s)^2+\zeta(2s)}{2}.$$
