Each citation must include the copyright symbol, name of the copyright holder (who may or may not be the author), and, if applicable, a statement that the use of the material or adaptation (in the case of adapted graphics) is by permission of the copyright holder.

Sometimes copyright holders will ask you to use a specific wording in your citation. If so, it's important to follow their instructions exactly, word for word.
