A circulation is the library management term for the loan of an Item to an Reader, with a set, calculated due date upon which it must be returned.

Circulations are recorded so that at any time it is possible to determine who is in possession of all Items recorded in the database.

A number of factors determine the calculation of the due date, including factors determined by the type of Reader, type of Item, and other factors determined by the environment and/or current time.
