As an aside, a possibly interesting read....

This is just an FYI: may be an interesting to read. Nothing Earth-shattering and, no surprise, the biggest problems for the digital preservation is the unique identification of books and DRM. But it is a good reference to have... (the first issue is clearly related to metadata, too).

Abstract:

This report discusses current developments and issues with which
public, national, and higher education libraries, publishers,
aggregators, and preservation institutions must contend to ensure
long-term access to eBook content. These issues include legal
questions about the use, reuse, sharing and preservation of eBook
objects; format issues, including the sometimes tight coupling of
eBook content with particular hardware platforms; the embedding of
digital rights management artefacts in eBook files to restrict access
to them; and the diverse business ecosystem of eBook publication, with
its associated complexities of communities of use and, ultimately,
expectations for preservation.
