I've got a client that publishes both "normal" trade books and also textbooks. They pay by the page, which generally works fine with the trade stuff, but with textbooks...yikes...double the trade rate isn't nearly enough. A dozen styles on a single page, not to mention tables and graphs and charts, oh my! Just wondering how anybody else handles these sorts of jobs or if there's any kind of industry standard that I don't know about. Wise counsel would be appreciated!
