We study the use of the Euler-Maclaurin formula to numerically evaluate the Hurwitz zeta functionζ(s,a) for, along with an arbitrary number of derivatives with respect tos, to arbitrary precision with rigorous error bounds. Techniques that lead to a fast implementation are discussed. We present new record computations of Stieltjes constants, Keiper-Li coefficients and the first nontrivial zero of the Riemann zeta function, obtained using an open source implementation of the algorithms described in this paper.
