They are not restricted to lace groups. The sites that have scanned books, not only lace but just bout any subject you care to name, are world-wide libraries where you can research a subject and read books, magazines and articles you may not have heard of or have access to, which has to be a good thing.
They are mainly based in the USA. Some are only available to professionals in their field. Some only allow you to read, others allow you to download. Some require a subscription/fee for some facilities, some do not. Individuals collect their particular field of interest into their own collection. They allow you to upload to share; sometimes you have to join to do so. Unfortunately it's not only the copyright owners who scan and upload. Any copyright owner can demand their material be removed if they find it has been uploaded. I've seen less than a dozen lace books. They are useful if a book you are thinking about buying is included on one of these sites and you can look before you buy, and also for a book which is unobtainable/out of print, but obviously there are some who will abuse it.
