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

The preservation of disk-based content at the British Library: Lessons from the Flashback Project
This article introduces the British Library’s Flashback project, which is exploring the practical challenges of preserving digital content currently stored on physical media (magnetic and optical disks). It reports on a Flashback proof of concept that conducted experiments on a sample of content from hybrid collection items dating from between... -

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 …
