I have a book that I have been wanting to write. Well it's almost entirely written. The thing is, when I came up with a title, I later found out that another author has a popular book with the exact same title. My topic is completely different, but it's the same title. Can I keep my title or do I have to change it? (Funny thing: I came up with another title for my book and it turns out that the same author has a book with that title too!) I wouldn't ask this normally. I would normally just go with it despite having the same name, but the book that already exists is popular and I don't want people to think that I titled the book the same way to get hits. By the way, my book has a subtitle too. And that part is completely different.
