There's an enormous amount of books, texts, and articles about hand-spinning, but most of these are about modern hand-spinning and not about historical techniques or their history. Historical spinning methods and tools, and the spun yarns made with them, have only gotten more attention in the recent years. So here are a few suggestions for further reading, should you be interested - including some publications with spindle whorls:
