The authors report {sup 13}C NMR line position, line shape, and spin-spin relaxation rate data for the quasi-two-dimensional organic superconductor {kappa}-(ET){sub 2}Cu[N(CN){sub 2}]Br ({ital T}{sub {ital c}}=11.6 K), for an aligned single crystal. The data make possible identification of the crystallographic site responsible for the NMR lines, clarify a line broadening transition near 150 K, and probe the nature of the fluxoid lattice below {ital T}{sub {ital c}}. {copyright} {ital 1996 The American Physical Society.}
