Hard to believe, I know. But the conclusion of Roberta Gelb in a recent Law.com article, Beware the Hidden Costs of Bad Formatting is that document formatting is not sexy. That said, it may save you money. Possibly lots of money, if Roberta's sums are to be believed.
The bottom line? Larger firms can probably save hundreds of thousands of dollars of wasted (unbillable) time if they adopt a smarter approach to document formatting. Not to mention lower rates of blindness and insanity, as their lawyers spend less time poring over fat documents, checking and re-checking all the cross references (Roberta overlooks this bonus in her article).
