Ninjutsu Training Techniques

Are there Different Variations of Ninjutsu/Taijutsu, ect styles?

Ever since I read a Manga (Basicaly comic book) called Basilisk I wondered. Cause there where different clan's fighting over who's stronger Koga and Iga. Anyways Im curious. anyone know of any books or Websites or DVD's on History/philosophy/and Application on how Ninja trained and there life styles? I'd Appreciate it much Thanks
