It's rather hard to know what is inside a lot of machine knitting books, because many of them are OOP (out of print). So you have no idea if you have picked up a bargain on Ebay. I was delighted to discover that another machine knitter has been writing mini book reviews.
Reviews in both German and English, by kind permission, from Kerstin of the Strickforum blog.
If you have a machine knitting book, that is not listed here, and you would like to post a review, please get in touch.
