Background: The German National Library
• Mandate: collect, permanently archive, bibliographically classify
and make available to the general public all German and
German-language publications from 1913
 Legal mandate covers “non-physical media works (online
publications)”
• Long term preservation at the DNB
– Since 1998: Voluntary deposit of e-theses; development of digital
publication collection and ingest workflow
– Since 2003: Development of a co-operative long-term preservation system
– Since 2009: Development of a long-term archiving service

Digital Rights at the DNB
• DNBG: “make available to the public” vs. copyright legislation:
“only with permission of the rights holder”
• Minimal access: 2 copies in parallel on “read only” computers in
the reading rooms
– Printing of up to 15% of the pages is allowed
• Beyond that, rights holders can grant
a) Access for registered users via internet
b) Unlimited access

DRM at the DNB
• DNB advises its deliverers to submit DRM free publications
• Since 2012, DRM mechanisms are detected automatically during
the ingest workflow
• DRM protected material is rejected and re-submission is
requested
• Why?
– DRM poses a risk to digital preservation
– DNB wants to preserve “unaltered originals” and abstains from
normalization measures during ingest ( Authenticity)

DRM at the DNB
• Data types that are occasionally submitted with DRM protection:
–
–
–
–
Doctoral theses
E-Books
E-Journals
E-Papers (digital versions of newspapers)
• Typical DRM techniques used:
– PDF document restrictions (password protection, print & copy restrictions)
– Adobe’s LifeCycle Management
– Encrypted ZIP containers

DRM detection at the DNB
• Regular unpack routine for ZIP containers uncovers encrypted
ZIP containers
• File Information Tools Set (FITS) with JHOVE, NZLZ Metadata
Extractor detects document restrictions
• Caution:
– Limited capabilities of the metadata tools
– Does every kind of restriction pose a risk to long term preservation?
– It is not always possible to get the publishers to submit DRM free versions

Challenges
• Increase and change of file formats and DRM techniques
• New technologies like tables PCs and portable E-Book readers
with new embedded DRM techniques
• Already archived objects with DRM protection:
– Between 1998 and 2012, DRM was only detected manually in sample
checks
 Not documented
 No statistical values available
– In 2014, re-ingest of old these material via the new and improved ingest
workflow that allows detection of DRM mechanisms
– DNB is entitled to remove DRM  Future project
