So What’s the Problem with E-journals?
• 96.1% of Science journals are online
• 86.5% of Arts and Humanities are online
• 2006-2007 – 102,000,000 downloads
– Up 21% from previous year
• 17% usage is at the weekend

Why Worry About Digital Preservation?
• Worries that all that is now digital may not always
be available, for a variety of reasons.
* Publishers ceases publication with no transfer
* Publisher goes out of business with no transfer
* Publisher taken over
• Works well with print via legislation and national
• Countries with legislation enacted (or ‘in train’)
for e-materials include: Canada, Denmark,
Finland, France, Germany, Iceland, New
Zealand, Norway, South Africa, Sweden, UK
• But, not all countries (notably USA) and in UK
the legislation supports voluntary deposit, with
restrictions of mode of access
Why a Preservation Registry?
• Many schemes emerging to meet challenge
• But who is doing what?
– How can libraries & policy-makers assess which
e-journals are being archived, by what methods,
and under what terms of access?
• JISC commissioned a scoping study for an
e-journals preservation registry
– the idea had been mentioned in the literature
Scoping Study Report Precedes PEPRS
• Rightscom / Loughborough University, 2007
– Confirmed expressed need among libraries and
– Warned of potential burden on digital
* an e-journals preservation registry should be built
* UK Union Catalogue of Serials (SUNCAT)
or SHERPA (Open Access) get involved
– SUNCAT is hosted and managed at EDINA
• Phase 1 funded by JISC (Preservation
Programme) from August 2008 – July 2010
• EDINA, University of Edinburgh, grant
• Project partner – ISSN International Centre,
• Evaluation carried out by Charles Beagrie
Limited for the JISC in February 2010
Digital Preservation Agencies in the Pilot
* Two 3rd Party Organisations
– CLOCKSS (Controlled Lots Of Copies Keeps Stuff Safe)
* Two National Libraries (c.f. legal deposit)
– British Library (BL)
British Library e-Journal Digital Archive
– Koninklijke Bibliotheek (KB e-Depot)
KB, National Library of the Netherlands
* One library cooperative
– UK LOCKSS (Lots Of Copies Keeps Stuff Safe)

ISSN Register - steps
• Step 1. Extract a record for each record
from an agency
• Step 2. Take the ISSN-L from each record
• Step 3. Parse the Register to map from the
ISSN-L to the associated ISSNs
• Step 4. Load the records into a PEPRS
database and link using the ISSN-L to the
table with the records from the agencies.
Example: a search on ISSN*
‘International Journal of High
Performance Computing Applications’
* ISSN-L is used within the system to
allow entry of either e-ISSN or p-ISSN
Finds the agencies looking after e-journal,
and the volumes being preserved
This displays what one of the archiving
agencies, does in terms of access
This allows a list of e-journal titles to be checked
Issues identified in Phase 1
• ISSNs used by agencies
• Holdings information supplied by the
• Vocabulary used by the agencies
• ISSNs missing in some agency records and
some not in ISSN Register
• Some duplicate records
• Some p-ISSNs used as e-ISSNs
• Some p-ISSNs linked via a common ISSN-L
to a number of e-ISSNs but which one is
• Some were incorrect
Holdings information - variation
e-Depot: Preserved: v. 1 - 36, 38 - 46.
UK LOCKSS Alliance: Preserved: v. 42 -
45. In progress: v. 46, 47.
Portico: Preserved: (2002-2009) v.40, v.41,
v.42, v.43, v.44, v.45, v.46, v.47.

Key recommendations from evaluation carried
out in February 2010
• Should be funding for 2 further years with an
initial 6 month phase and then if reviewed
successfully for another 18 months
• Need to resolve with the agencies currency
and updating of agency statements,
archiving status and fields and terms to use
• Continue with the development platform until
the end of 2010
• Establish a governance structure
PEPRS Phase 2
• Funding provided from August 2010 – July
• Beta service – late 2010
• Full service – late 2011?
• Involve international users in testing

Involvement with international initiatives
• Print Archives Program of the Center for Research
Libraries – “CRL is working with consortial partners to plan a
prototype print archives framework to link existing print archiving
efforts. has developed a searchable Print Archives Registry of
information about print-archiving initiatives, including:
– Serial Holdings.
• HATHITrust – “….is committed to preserving the intellectual
content and in many cases the exact appearance and layout of
materials digitized for deposit. HathiTrust stores and preserves
metadata detailing the sequence of files for the digital object”.
