Original printer: http://www.kirjaboek.nl ... Reseller: http://www.bol.com/ (They say it is a hard-cover, but i have no confirmation of that being accurate, so don't blame me if it is a soft-cover.) You could print and distribute it too if you like. Go to free PDF downloads: here This books as it is sold does not have the latest (few) changes, see: ../gratis/Notice.html about these changes. Hopefully a later version (#2) of this book will contain them.
