Recent measurements of inclusive and exclusive semileptonic b branching ratios are reviewed. Model-independent analyses from ARGUS and CLEO connrm the value B(b ! ``X) = 10:4%, while new analyses from ALEPH obtain higher values above 11%. The diierence is not consistent with measured values of b hadron lifetime. New measurements of B(B ! D ? ``) from CLEO and ALEPH are in good agreement. First ...
