On Choosing A Preservation File Format for Video: “TIFFs are too big to store”, or “We Used JPEGs and Nobody Died”

George Blood, President
What librarian hasn’t struggled with storage capacity? Ever larger library buildings and ever higher data densities have not solved the fundament problem in the cultural heritage field: Information takes up space. Care in acquisition and prudent deaccessioning help, but stuff keeps coming. While storage becomes more efficient and cheaper every day, the fact that it will be easy to store digital video in 20 years doesn’t help us today – in 20 years most legacy video formats will be inaccessible as machines die of old age. What then do we do now? If you cannot afford 10-bit uncompressed files (at a whopping 100GB per hour), and you lack the IT infrastructure to support JPEG2000/MXF, how are you to preserve video today. This talk will explore some of the considerations on the slippery slope of choosing a compressed format for storing moving image collections.

What goes where? Bringing a new repository online at the Ohio State University Libraries

Emily Shaw, Head, Preservation and Reformatting
Like most libraries, the Ohio State University Libraries did not enter the digital library sphere with clear policies and a unified, interoperable infrastructure for managing all of our digital collections. The Libraries has a long-standing commitment to making our unique collections accessible to the campus and global communities and maintains an expertly managed and curated Institutional Repository (the Knowledge Bank). But for more than a decade, OSU’s digital collections developed in response to the requirements of specific projects. Thus, for the past several years, the OSU Libraries has been investing heavily in the planning and development of a robust repository infrastructure to enhance access, management and preservation of digital collections of all types. This presentation will give an overview of our planning process and share some of the workflow documentation currently under development.

Letting somebody else do it.

Frances Harrell, Preservation Specialist
In 2014 The Jamaica Plain Tuesday Club (JPTC), an all-volunteer history and culture organization in Boston, had a selection of their archives digitized by the Boston Public Library, the images transferred to the Digital Commonwealth preservation repository, and the associated metadata aggregated by the Digital Public Library of America. As this model of aggregation grows through the influence of the DPLA, small organizations like this with digital collections will increasingly depend on their colleagues at larger institutions to shoulder the burden of long-term preservation. Using the JPTC as a case study, this talk will take the perspective of the small organizations who want to see their collections increase in reach and impact, and will raise some of the difficult questions the preservation field faces in attempting to steward the digital heritage of these limited-resource compatriots.
