but on the path. This very large (33" or 85cm when opened) and substantial at 2lb 14oz / 1.3 kgm (not the 1lb shipping weights Amazon claims) book is not for every use. Do you have a 1 foot by 3 foot flat clear space on your desk? I haven't seen that much open space on a desk since Mrs. Roberts would use a ruler across the palm of any miscreant who dared violate her tidiness ordinances.  I'm sorry! Mercy! Please mercy! Whack. Whack. Whack. Ahh, the pleasures of grade school. So, lacking Mrs. Roberts to give order to my life, I use this book with one end in my lap and the other propped against a desk or table.
