Hi I have a 240 page manuscript, and am searching for a publisher. When setting up the formatting, I extensively researched the proper format, and the unanimous advice was that colons, semi colons and em dashes should ALL be replaced with em dashes. I cross referenced this exhaustively, but every website gave the same advice. Okay, but now I'm considering self publishing ... and suddenly I'm faced with the daunting task of "reverse engineering" this manuscript and finding every single em dash, and making a decision on each one as to whether it remain an em dash, or be changed to either a colon or semi colon. Has anyone had this experience, and if so, what was your solution? Thanks much!
