The Flashback Project: Rescuing disk-based content from the 1980s to the present day
This paper introduces the British Library's Flashback project, a proof-of-concept that explored the practical challenges of preserving digital content stored on physical media (magnetic and optical disks) using a sample of content from hybrid collection items dating from between 1980 and 2010. It describes some of the activities undertaken by...Pennock, Maureen ; May, Peter ; Day, Michael ; Davies, Kevin ; Whibley, Simon …

Practical analysis of TIFF file size reductions achievable through compression
This paper presents results of a practical analysis into the effects of three main lossless TIFF compression algorithms – LZW, ZIP and Group 4 – on the storage requirements for a small set of digitized materials. In particular we are interested in understanding which algorithm achieves a greater reduction in...May, Peter ; Davies, Kevin
