What are the different bonsai schools out there?

Hi all,
I've got contacted by a group of students doing a research on bonsai of their journalism course.
They are asking for info on the following topics which I need to provide materials by end of this week [ friday evening ]:
[ I'll post in fr and en, feel free to answer in fr if you are more comfortable ]

FR:
Les écoles de bonsaï
Les types de coupe pour bonsaï
Les plantes le plus adaptées pour le bonsaï

EN:
The types of bonsai "schools"/"approaches"
The types of cuts used in bonsai
The types of plants that are the most appropriate for bonsai

I'm digging up materials on my side, but I would not mind having some extra opinions or points of views.

Thanks in adv.

The "schools" question could take off in any number of directions. Can they be more specific?

On a broad sense, there is the:

1. Japanese "school" of bonsai -- very traditional and manicured; relatively small group of trees used.
2. Chinese "school" -- more freedom in design; less manicured. Possibly a wider use of varied species. A few "sub-schools" -- lignan, north China vs. south China, etc. More imaginative use of landscape designs.
3. "Western school" -- somewhat imitative of (primarily) Japanese thought, but more willing to innovate with such sub-groups as "naturalistic" trees; much wider use of varied species.
4. - ??????????

Feel free to disagree, modify or expand . . .

Thanks Jim, its been very helpful.
I've come across the following:
*) Japanese Traditional - basically anything pre-Kimura (~1985 or so) - John Naka
*) Japanese Modern - anything post Japanese Traditional - Kimura
*) Keshiki bonsai - Kenji Kobayashi, Kaori Yamada
*) Saika bonsai - Kaori Yamada
*) Mambonsai [ ?? ]

Last three are definitely not my cup of tea
