Where can you read a book on how to draw manga for free?

well, there are a lot, but i prefer how to draw manga.com or draw manga.com.

白泉社 Hakusensha, the publisher of LaLa and Hana to Yume serialization magazines, and manga series such as Gakuen Alice, Kaichou WA Meido-sama etc recently started a step-by-step tutorial on their web using the series 少女まんが家になろう！shoujo mangaka ni narou

The tutorial currently (Apr 2010) has only 2 steps, but the tutorial is scheduled to be updated once a month with new steps.

Follow the link in the related links below

1. click on step 1, it should lead you to web page
2. click on the '試し読みする' open book symbol to read it, wait for the download to complete
3. once the first page is loaded (showing the first page of the manga drawing), look for the left hand navigation panel
4. '進む' means forward, i.e. next page, '戻る' means previous page, '閉じる' means close the window

The catch? Everything is in Japanese language.
