A consultancy paper for the Welcome Library - The Wellcome Trust is developing a digital library over the next 5 years, anticipating a storage requirement for up to 30 million images. The Wellcome previously has used uncompressed TIFF image files as their archival storage image format. However, the storage requirement for many millions of images suggests that a better compromise is needed between the costs of secure long- term digital storage and the image standards used.

Stanford University Libraries is now maintaining Image defects pages as a first step in sharing our digital preservation program’s best practices for imaging and quality control.
This collaborative resource currently includes just under 100 examples and will continue to grow with support from the library and cultural heritage communities. Examples are described (and sortable) by “look” and by “cause”.
