In this paper we give a refinement of the bound of D. A. Burgess for multiplicative character sums modulo a prime number q. This continues a series of previous logarithmic improvements, which are mostly due to H. Iwaniec and E. Kowalski. In particular, for any nontrivial multiplicative character χ modulo a prime q and any integer r≥ 2, we show that ∑_M
