I recently purchased a copy of Working Dogs of the World from a London bookshop.
This book was written by C.L.B. Hubbard and published by Sidgwick and Jackson Limited of London in 1947.

The beginning paragraphs of the section titled Collies
The Scottish Collie is probably the best-known Sheep-dog in the world, and certainly the most popular in the English-speaking countries. The race is extremely old, even among the breeds of Scotland, all of whose dogs are or ancient lineage. The modern Show-type Collie is, of course, a comparatively recent creation, but the old Working Collie is still very much like the type called 'Shepherd's Dog" by Dr. Caius in 1570, and by Buffon and other naturalists centuries ago. Indeed, the Working Collie shows much its make-up of the primeval dog.
