You shouldn't need to spend so much time fussing with complex software just to compile a co-authored book.
My grandpa was turning 88 when my grandma reached out and asked if I could help her make a book for him for his birthday... Her idea: "The people he's made an impact upon throughout his life could each contribute a little statement"
He is a special man, and people sure let him know it! He was SO touched, as was my family & I. So, I made it super easy for others to make a crewbook.
