At 9:45 PM yesterday, I finished Drupal for Humanists. It came in at 104,658 words, 91 images. The addition of even a brief glossary (requested at DHSI) necessitated even more extensive cutting; ThemeKey and Views Bulk Operations had to go, along with configuring multi-author nodes and showing the number of nodes associated with a taxonomy term. All told, there's now 9,777 words of supplementary material that will be coming to the site soon.
The double-spaced version requested by the publisher takes up 459 pages-- just 41 pages shy of a full ream of paper.
