Book excerpt: In this note, recent results of studies of semileptonic B meson decays from BABAR are discussed and preliminary results given. In particular, a recent measurement of?(B → D{sup (*)}??) and the ratio?(B → D{sup (*)}??)/?(B → D{sup (*)}l?) is presented. For the D* mode, a branching fraction of 1.79 ± 0.13(stat) ± 0.17(syst) is found, with a ratio of 0.325 ± 0.023(stat) ± 0.027(syst). For the D mode, the results are 1.04 ± 0.12(stat) ± 0.14(syst) and 0.456 ± 0.053(stat) ± 0.056(syst), respectively. In addition, a study of B{sub s} production and semileptonic decays using data collected in a center-of-mass energy region above the?(4S) resonance is discussed. The semileptonic branching fraction?(B{sub s} → l?X) is measured to be 9.9{sub -2.1}{sup +2.6}(stat){sub -2.0}{sup +1.3}(syst).
