The link you give involves other programs besides Word. Two of these program links don't work ( CocoaBooklet and Booklightning)! Are you telling me that the Mac version of Word will not produce a booklet? Are you telling me that the only way is via a program that converts pdf into booklets?
Thanks for your help. Take your fee! At least I will now be able to do the task and stop wasting time trying to do it directly from Word.
