In this paper, we compare the interlayer transport in the organic superconductor {kappa}-(BEDT-TTF){sub 2}Cu[N(CN){sub 2}]Br on samples of different inhomogeneities in terms of resistive transition width {Delta}T. For field parallel to the current, H{parallel}I, in the direction perpendicular to the layers, the isothermal magnetoresistance R(H) displays a peak effect as a function of field for high quality samples. The peak effect decreases gradually with increasing {Delta}T and it disappears completely for the sample with {Delta}T{gt}2 K. The results demonstrate clearly that the peak in R(H) in the interlayer direction is intrinsic to the layered structure in this compound. {copyright} {ital 1998} {ital The American Physical Society}
