The successful preservation of digital assets requires maintenance, continuity of service, and proactive stewardship.1 An ongoing challenge for Bodleian Libraries (of Oxford University) and Cambridge University Library (CUL) has been taking outputs from time-bound digital preservation projects and turning them into ongoing uninterrupted services. This is not a challenge which is specific to Bodleian Libraries and CUL, but it has been recognized as a difficult transition for many organizations to make. The Digital Preservation at Oxford and Cambridge (DPOC) project (2016–2018) is a collaboration between Bodleian Libraries and CUL which is supported and funded by The Polonsky Foundation. Bodleian Libraries and CUL have historically strong ties, and have previously collaborated on digital preservation projects. Both organizations also have experience creating digital preservation resources, for which stewardship at the end of projects has been transferred over to staff within the libraries for maintenance. However, siloed preservation activities have so far not translated into institution-wide, ongoing programmatic digital preservation activities.
