Informative , reasonably self contained at least at my level of prior knowledge and mainly not necessary to have any 'in depth' special knowledge of Lie groups , and goes into enough detail to follow some relations not normally given in other texts. Would recommend this book. Would rate it higher if it were not for the numerous errors - quite a few of them. If any question and it seems perhaps error to you may bring it up on math overflow stack exchange citing the explicit page and eq. number etc. and maybe i can help.
