New works of art and research are based on the works that came before, but copyright law can limit a creator's access to these works. As Judge Joseph Story noted in 1845:
“In truth, in literature, in science and in art, there are, and can be, few, if any things, which in an abstract sense, are strictly new and original throughout. Every book in literature, science, and art, borrows, and must necessarily borrow, and use much which was well known and used before.”
The fair use exemption exists for just this reason.

The Fair Use Evaluator (see below) provides a guide to these steps, and creates a (non-legally binding) evaluation form at the end. Fair use tends to be decided by the courts on a case-by-case basis, so there's no single formula that will decide if a use can be considered fair or not.
