As long as you know what this book is, you'll be very pleased with it. Note the subtitle very carefully - 25 Years of Articles, Techniques, and Expert Advice. It's a collection of articles from 25 years of Vogue Knitting magazine, written by their most impressive contributors - lots by Meg Swansen and by her mother Elizabeth Zimmermann, some by Mary Lynn Patrick, Barbara G. Walker, and single ones by Melanie Falick, Barbara Albright, Lily M. Chin and others. It contains a lot of information about techniques and unless you're actually Meg Swansen, you will learn a lot from it. There are profiles of some knitting designers too, female and male.
What it isn't is a sumptuous collection of photographs of gorgeous knitted garments that compel you to pick up the needles, or patterns for fabulous sweaters; there's little to drool over here. However, it is designed like a sumptuous picture book and not as something to be read, which is why I've taken a star off. It uses a typeface which is too small to read comfortably but which takes up a lot of space, not a good font for text, and most of the headlines are in pale colours like custard yellow or sage green. Some of the instructions which accompany the illustrations (which are very clear) are in tiny type, surrounded by lots of white space - this is the wrong way round.
All of the articles have references so that you can find the original if you have the complete run of issues of the magazine: this has been done thoroughly and makes the book a very useful partial index to the magazine itself. The book also has a good index.
I think it's going to be very useful to me and I'm looking forward to reading it more carefully, but I wish it was going to be easier to read, and to refer to when I have needles in my hands.
