ReVerDi — Real versus Digital

Sustainability optimisation in national libraries

How should national libraries balance their physical and digital collections? We assess all three pillars of sustainability together — environmental, economic, and social — across Switzerland, the United Kingdom and the Netherlands.

The challenge

Sustainability & national libraries

National libraries safeguard a nation's published heritage — and increasingly hold it twice: on shelves and on servers. Growing digital collections require ever more infrastructure, energy and cost, while physical items must be preserved indefinitely for legal, scholarly and cultural reasons. ReVerDi asks what an optimal mix of physical and digital looks like, and measures it across three dimensions at once.

E

Environmental

Energy, CO₂, water and resource use across the full life cycle of physical and digital media.

Economic

Investment and operating costs — and the public value libraries create for society.

S

Social & cultural

Access, inclusion, working conditions and the safeguarding of cultural heritage.

The consortium

Partners

A collaboration between applied research and the national libraries themselves.
