I recently updated the Preserv bibliography for the first time in nearly a year. Hence, for those following KeepIt but not the earlier Preserv project, you may not have come across it
It may be, currently, the most extensive bibliography on digital preservation, perhaps. Yet it isn’t comprehensive because it sees DP mostly through the prism of what might be relevant to repositories, particularly institutional repositories, and covers technical and other factors relevant to creating digital preservation services.
You mighty also argue that it can’t be comprehensive because it doesn’t include the papers in the KeepIt wiki bibliography, which follows the data structure – arts, science, teaching – of the project’s exemplar repositories. The two bibliographies are largely mutually exclusive, and complementary.
