Encyclopedia of Needlework by Thérèse de Dillmont (1846-1890) has been published online as a web site.
Usually online books are delivered as PDF files which are easy to download but still a bit unwieldy and costly to print out. It is really handy to have version as a website, as you can pop online with a search function check something quickly.
The book consists of 16 chapters that range across many areas of needlework. For anyone looking for pulled and drawn stitches there is a chapter on Single Cut Openwork and a chapter on Whitework which is useful. Under Miscellaneous fancy work there are some interesting techniques along side some canvas work stitches.
