6.7 Boundaries between Items

The boundaries between moving image Items is determined primarily by the boundaries between Manifestations (see Boundaries between Manifestations). There may be multiple Items associated to a Manifestation that are, for all intents and purposes, exact copies, but which may have small differences that do not necessitate representation as a Manifestation. For example, an institution may have two DVD-R copies of the same Manifestation, with cosmetic differences in their labels.
