Arrange­ment is the order of the mate­ri­als in a col­lec­tion. Some­times, the arrange­ment of the col­lec­tion is an exact rep­re­sen­ta­tion of how the cre­ator kept it. Other times, an archivist or inter­me­di­ary put mate­ri­als into a dif­fer­ent arrange­ment. Usu­ally, records are arranged as a hybrid of what worked for the cre­ator and what the archivist antic­i­pated would make sense to users.
