The other two are from the same author, Robert Steven. He has a nursery in Jakarta. I was lucky enough to track it down and took some great photos of a few of his trees. He is regarded as an excellent bonsai artist around the world. He is not so traditional and has created some magnificent trees.

Bonsai Techniques I by John Yoshi Naka
Bonsai Techniques II John Yoshi Naka
These books are excellent. Some of the best aspects of these books are how the author follows trees throughout many years and the pictures clearly show the different stages of development.
The last one of my favourites is an old bonsai book that I bought on ebay for $5.
The title is Bonsai Culture and Care of Miniature Trees. It is published by Sunset Books.
I love this book as it does a great job of explaining techniques very clearly. I particularly enjoyed reading this section -
"Bonsai are not exact duplicates of trees growing in the wild. Rather, they are evocations of the spirit of nature, of the life force of the natural world. They are man made shapes that suggest nature - as does, say, an impressionist painting - rather than duplicate nature, as a photograph might. The artist's feeling for balance, form, and line combine with nature's juices to evoke a larger and deeper concept."
