I'm doing a biography on Judy Blume. What would be a good title for the book cover?i also need to make a birth certificate so how can i do that
I believe you mean biography, not bibliography. You might take a look at the notes on "about the author" for which I included a link, but you might call it: Judy Blume: A child of suburbia. She refers to herself with this term. Or you can use a title from one of her books such as "Are You There World? It's Me, Judy Blume." Or, "Judith's House" after her book Iggie's House.
As far as a birth certificate, try looking at the templates that Mircosoft Office provides through Word. I'm sure you can find a template that would work. You can also get the facts to include on the certificate from the link below.
