This is a product of London in the 1990s, ascribed to Kenneth Harding, which was one of the many pseudonyms used by Paul Little in his erotic writings, particularly when spanking was involved. I haven't yet seen Volume 1, but it is likely that both relate investigations into what might be called the 'social' side of the topic, describing activities in clubs at which enthusiasts gather. Perhaps the earlier work deals with the UK, since Volume 2 deals with goings on in USA and mainland Europe. Disciplinarian private schools are included. The treatment is not particularly erotic, being fairly factual and catalogue-like in approach, and it is consequently an unexciting book, perhaps of interest only to the true aficionado. ( )
