The Six-and-a-Half-Hour Bookblock

I did a 400-page bookblock today — 400 pages! —designed it, put it together, adjusted the design a bit, then adjusted the design a bit more, all in a day's work. (Out of deference to the author and publisher, the title of the book will not be disclosed.) Mind you, it had no photos (which is unusual) and it was fairly easy to format — but it was still a labor-intensive process, and it's been a very long day.
