abstract = {By applying the "coefficient extraction method" to the symmetric transformation of hypergeometric series due to Chu and Zhang (2014), we examine systematically five classes of infinite series of convergence rate "   −  1      /    4" containing binomial coefficients and harmonic numbers. Numerous closed formulae in terms of universal constants (such as    π,    ln  ⁡  2, and the Riemann zeta values) are established.}
