Contacted the print shop, gave them last time's invoice number and they generated a new quote for me including the spine width for the number of pages this time. Did one iteration of the cover, then found an error in one of the articles which affected the title, so had to regenerate the TOC and build the new one into the cover. Should be good to go now, unless there are pagination changes. Also fixed a bug in programming which was neglecting to include the bio for the editor, who also has an article in there so needs to be included.
