There are significant technical, financial and legal obstacles to digital preservation.
This Report focuses on the law – in particular, on copyright and related rights issues. As the laws of the countries discussed in the report demonstrate, in many cases exceptions and limitations do not accommodate the actions required for digital preservation. The copyright and related rights issues, and various strategies to address them, are discussed in detail in the report.
