  We establish some identities of Euler related sums. By using these
identities, we discuss the closed form representations of sums of harmonic
numbers and reciprocal parametric binomial coefficients through parametric
harmonic numbers, shifted harmonic numbers and Riemann zeta function with
positive integer arguments. In particular we investigate products of quadratic
and cubic harmonic numbers and reciprocal parametric binomial coefficients.
Some illustrative special cases as well as immediate consequences of the main
results are also considered.
