The input to each volume consists of 1000 pages of text typed 10 characters to the inch, 6 lines to the inch, on 8.5-by-11-in. paper with 1-in. margins on each side. Each volume also has about 100 pictures, which will be displayed in color at Super VGA resolution (1024 ~ 768 pixel, 8 b/pixel). Moreover, each volume is enhanced for the CD version with 30 min of audio of teleconferencing quality (16,000 smp/s, 6 b/smp).
