The term preservation defines those actions taken to care for or safeguard (something) against deterioration. When applied to Cultural Heritage, preservation may involve methods of minimising risk of loss, slowing physical deterioration, and optimising the conditions that ensure the maintenance of the integrity of the heritage asset. In this sense preservation is not only physical but may include methods to safeguard the information about a particular heritage object or practice, including proper documentation through digital methods. Preservation is a future-oriented concept that seeks to safeguard an heritage asset for future generation. Preservation is sometimes used interchangeably with the term ‘conservation’.
