This presentation on the new edition of the Digital Preservation Handbook was given at the DCDC15 conference in October 2015. Originally published in 2001 as a paper edition, ‘Preservation and Management of Digital Materials: a Handbook’ was the first attempt in the UK to synthesise the diverse and burgeoning sources of advice on digital preservation. Demand was so great that in 2002, a free online edition of the Handbook was published by the newly established Digital Preservation Coalition. After more than a decade, in which digital preservation has been transformed, the Handbook remains among the most heavily used area of the DPC website. Funders and organisations are collaborating on re-designing, expanding and updating the Handbook so it can continue to grow as a major open-access resource for digital preservation. The slides provide a detailed overview of the new edition Handbook and work in progress.
