Like many academic and research libraries, the University of Notre Dame's Hesburgh Library collection has evolved over the last twenty years or so from analogue to increasingly digital, and from a physically owned and locally stored collection to a broad range of both local and external resources, organised around users’ needs.

The complexity and varied nature of our collection means this is no one- size-fits-all digital preservation approach. Different strategy is required dependent of the significant properties of the collection items.

To gain a better understanding of the Library’s overall digital content, and to help plan for digital preservation, we recently co-led a project at Hesburgh Libraries, University of Notre Dame, where we developed a Typology of Digital Collection as a framework to guide digital preservation.

On this World Digital Preservation Day, we’re here to remind you of the humble floppy disk, last century’s save icon. Though limited in terms of capacity, these inexpensive and lightweight disks were the dominant storage device for three decades, as is evidenced by the boxes of floppy disks now found among the stacks of most archives. Among the disks at Emory University are files created by novelist and Pulitzer Prize winner Alice Walker, poet and former US Poet Laureate Natasha Trethewey, poet and writer Lucille Clifton, and the Southern Christian Leadership Conference (an Atlanta-based organization founded in the wake of the 1957 Montgomery Bus Boycott under the leadership of Dr. Martin Luther King). Unfortunately, the deterioration of such magnetic media due to age and poor storage conditions has been difficult to avoid and, with even the youngest of these disks now approaching twenty years old, recovery of data frequently proves challenging.

Digital preservation is about conveying meaningful information between contexts over time [1].  A great deal of the complexity stems from digital information residing at multiple levels of representation [2]  This process is never free.  It requires resources (human, technical, financial).  Ensuring a steady flow of resources over time is difficult. 

At any given time, dedicated individuals and informal groups play a vital role in the provision of resources (collecting, organizing, storing and sharing information in which they have an interest).  Commercial providers of information systems also play a major role, by providing the platforms upon which consumers create, manage and share information.

Como comunidad enfrentada a la responsabilidad de preservar la memoria de nuestras respectivas organizaciones, nos ha tocado una tarea difícil. Casi la de adivinos. Cuando hablamos de la preservación y de proteger y poner a disposición “para siempre” nuestra historia - en el medio que sea se haya originado, papel, objetos, audiovisual, etc. - dichas palabras nos quedan grandes. Hay mucha incertidumbre en ese “para siempre”. Sin embargo, hemos sido capaces de encontrar juntos poco a poco la respuesta a nuestras necesidades, y seguimos construyendo en esa dirección. Las comunidades son de suma importancia en nuestro quehacer, y cómo hemos dado forma a nuestra disciplina a pesar de esa incertidumbre. ¿Será que un enfoque comunitario es la respuesta a nuestras necesidades en preservación digital?

When announcements of the nominations for the 2018 DPC digital preservation awards appeared, it was hard to believe two years had passed since (as hopeful nominees), we entered the grand marble foyer of the Wellcome Trust HQ. The list this year is truly impressive. The scale of the digital preservation challenge can obscure the fact that there are so many amazing projects and initiatives underway. Projects that are tackling sustainability, driving skills development and addressing the trickiest of quandaries through imaginative and applied research. It is both crucial and excellent that this work is being celebrated, recognised and shared.

Every issue of the New Humanist and its predecessors dating back to 1885 is now available through the state-of-the-art digital edition developed in partnership with Exact Editions. We like to think that those historical issues have now moved into the ‘safe pile’. In their digital format, they will stride forth into the future to be read by new generations of readers and thinkers.

Libraries and digital preservation go hand in hand in Scotland. All across the country there are exciting initiatives ongoing in organisations such as the National Library of Scotland as well as Scotland’s thriving network of public and university libraries: ground-breaking projects only made possible because of the skills of Scotland’s library and information workforce.

With all the work that is going on we at CILIPS became aware that our own organisation did not have a strong digital history. Despite being over 100 years old (previously the Scottish Library Association) all our history was held in archives on site or with the National Library. With that in mind we decided to look at creating a digital archive via a timeline and highlighting notable people.

Some time back long term data sustainment lost the attention of my main funders, so last month - when I retired - I thought I'd have a chance to return my attention to it properly. Unsurprisingly, my immediate attention has been taken up with VAT returns, no longer putting off redoing the kitchen and the magnificent local buzzards circling low overhead.

Attending to the right thing is not straightforward. A colleague once said that a managing director should have nothing on their desk, otherwise that becomes locus of their attention rather than the future of the company. Look at any Computer Aided Design (CAD) demo and your attention will be drawn to a complex 3-D part rotating to show itself off. However, the future in CAD lies in the change from drawings to models, something only hinted at by the dull text boxes at the display's edge and which did not grab your attention. Although early CAD did replaced the drawing board, the modern CAD model replaces the model shop where  skilled craftsmen would construct wooden mock-ups, For example, Airbus created a full scale mock-up of the A340 wing, said to cost a million pounds, but saving several times that through design improvements. Now model-based CAD saves the cost of building those physical mock-ups.

Everyone tells us we live in a digital world and to a certain extent this is true. As a librarian, I first started creating digital content in the 1990’s and looking back, what we were doing then, does look so last century now. These are the digital dark ages and yet the content which was created remains as relevant now as it was then. So much has changed in a few decades and how expect to access content has changed too.

I feel that there is an increasing disconnect between the digital artifacts that we capture and the mechanisms used to create the knowledge that they embody. This contributes to some of the difficulties with preserving these born-digital materials in a way that effectively retains their meaning.

The seed for this train of thought has been my involvement in the Cultures of Knowledge project and the accompanying online resource Early Modern Letters Online (EMLO). The aim of the project is to use digital methods to reassemble and interpret the correspondence networks of the early modern period (roughly 1550-1750). This period is interesting in that it saw the emergence of a significant social network across Europe and the associated Empires, enabled by the development of postal services and increased population mobility. This resulted in an explosion of intellectual activity that laid the foundations for the Enlightenment and established patterns for scientific discourse that persist until the present day - for example, the foundation of The Royal Society and the publication of the first scientific journals.
