IDENTIFYING THE VARIETIES
Lorelei Halley's pinterest page: https://www.pinterest.com/lynxlacelady/ You need a pinterest account to see my boards, but joining is free. I have a board for each type of lace.
Rosemary Shepherd's article: http://www.powerhousemuseum.com/pdf/research/classification.pdf
Many photos, varieties of bobbin lace: http://lynxlace.com There are pages also for each major kind of lace.
A good way to learn to identify laces is to look at lots of photos of high quality antique laces. http://lacenews.net/ has a section on "ebay alerts" with photos and descriptions of current offerings. I have found the best way to see detail shots is to click on the photo, wait till the ebay page comes up, click on "enlarge".
http://www.laceforstudy.org.uk/ Many of the photos show very fine detail. The site has a search function, so you can ask for photos of just Chantilly, for instance, or Duchesse.
LePompe 1559: You can now see both volumes, actually the ones Mrs Palliser had seen at Bibl. Arsenale. The order of the pages are different, but it is the pages we know from the published versions. They are online thanks to Bibliothèque nationale de France:
