Looking for a book or online resource for learning Japanese

I'm taking Level 1 this year and I'm looking to better understand the kanji. My electronic dictionary had a feature that showed the etymology of the kanji -- the evolution of the kanji over time -- but that dictionary died long ago. I'm writing here to ask:

What is such a book called in Japanese.
If you know of any online versions.
If you have any recommendations for such a book or software.

I got the resources here:
