53. Material Substitution

Selective depository libraries may substitute tangible commercially produced products (e.g. microforms, DVDs, etc.) or online content, for any depository holdings held in the library for at least one year. Depository material being substituted with online content must meet official substitution criteria. Permission to substitute must first be obtained from the regional depository library. Substituted material is subject to the same rules and regulations that govern the care, treatment, and public access while the library holds the material or until the regional depository library has authorized for the withdrawal of it.
