Stef,

> hi yoshiki do you have pointers to these books?

  The best one is the book by Umezawa-san:

http://www.amazon.co.jp/%E8%87%AA%E7%94%B1%E8%87%AA%E5%9C%A8Squeak%E3%83%97%E3%83%AD%E3%82%B0%E3%83%A9%E3%83%9F%E3%83%B3%E3%82%B0-%E6%A2%85%E6%B2%A2-%E7%9C%9F%E5%8F%B2/dp/4883732037/ref=pd_bbs_sr_1/503-8091051-3770302?ie=UTF8&s=books&qid=1192354523&sr=8-1

From the very basic Squeak Smalltalk programming to Monticello to how
to create VM plugin.  So much stuff aboutf Squeak is covered in this
600 pages book.

  And of course for Etoys, the one by Yamamoto-san:

http://www.amazon.co.jp/%E3%82%B9%E3%82%AF%E3%82%A4%E3%83%BC%E3%82%AF%E3%81%A7%E3%81%82%E3%81%9D%E3%81%BC%E3%81%86%E3%80%90CD-ROM%E4%BB%98%E3%80%91-Thoru-Yamamoto/dp/4798104809/ref=pd_bbs_2/503-8091051-3770302?ie=UTF8&s=books&qid=1192354523&sr=8-2

A cute picture book that introduces the features of Etoys.

  These two are worth to mention in a flyer like Damien's.

  There are a few other books:
