Book excerpt: The authors present preliminary measurements of branching fractions and charge asymmetries for the B meson decays B[yields][eta][prime] K*, B[yields][eta][prime][rho], and B[sup+][yields][eta][prime][pi][sup+]. The data were recorded with the BABAR detector at PEP-II and correspond to 89 x 10[sup 6] B[bar B] pairs produced in e[sup+]e[sup -] annihilation through the[Upsilon](4S) resonance. They find the branching fractions[Beta](B[sup 0][yields][eta]K*[sup 0])= (19.0[sub -2.1][sup+2.2][+-] 1.3) x 10[sup -6], [Beta](B[sup+][yields][eta]K*[sup+])= (25.7[sub -3.6][sup+3.8][+-] 1.8) x 10[sup -6] with 90% confidence, and[Beta](B[sup+][yields][eta][prime][pi][sup+])= (2.8[sub -1.0][sup+1.3][+-] 0.3) x 10[sup -6] (
