I have my columns set up, but I need to write on both sides of paperl I can figure that out, if I just get the correct setting to write a book.
Write it as you would any book.
What do you mean? When you print duplex (double-sided), text is printed on both “sides”, recto and verso.
To get really useful help, mention OS name, exact LO version and save format (.odt vs .doc(x)). The latter is very important because you’ll really benefit full comfort and automation if you save native, i.e. .odt.
