Modern prompt books will tend to be constructed using binders with multiple tab dividers, with the page of the production attached to a larger sheet of paper to provide more margin space for taking notes.

In 2016 Coppola released a published replica of this prompt book as The Godfather Notebook as well as a signed $500 limited edition in a three-ring binder.
