A relative (who is no longer living) wrote a number of autobiographical pieces which I would like to publish in a book. They're very good but they need a fair amount of editing. I would like to include some chapters written by myself, that would supplement the relative's memories. How to I put my name on the cover and title page? If I were only writing one chapter, I could call that an epilogue and say:
edited and with an epilogue by Aparente
But this won't work if I contribute three or four chapters.
