Format shifting is central to preservation and archiving, particularly for sound recordings and films. In addition to efforts to preserve works created in deteriorating formats format shifting is also necessary to keep works accessible. As technology develops the technical formats get outdated and the technology necessary for accessing original formats is no longer available. Copyright law of the United Kingdom does not allow libraries and archives to format shift for preservation and archiving purposes. By the time copyright term in a work ends the original work may have disintegrated or deteriorated to such an extent that the cost of preservation increases.2
