Please note that when Sue "re-formatted" the Lulu version of DBA 3.0 it was not a great success. My copy had a badly cropped cover, distorted diagrams, and footers very close to the text despite lots of white space below.
The diagrams were the biggest shame. The error was caused by a lazy global re-sizing of the page dimensions. As the vertical and horizontal changes weren't equal the images for the diagram were distorted: very off putting.
