Welcome Interweave Crochet readers! If you are looking for my reviews of '70's crochet books, just click on "70's Crochet Read-Along" in the right hand column of this blog (it's the 3rd clickable link down from the top).
I have one more crochet conference to attend this year and then I can get back to reviewing '70's crochet books. In the meantime I've read a few 21st century books on yarn and color: The Yarn Book by Penny Walsh (read an excerpt here), and Color: A Natural History of the Palette by Victoria Finlay. (You can read an interview with the author here.)
You can also read CPer JD Wolfe's reviews of some '70's crochet books here.
