Overview/Background

Why are we up here?  Warning: WE’RE NOT EXPERTS!  Rice and Indiana Universities are both users and members of LOCKSS, CLOCKSS and Portico  We hear people from various libraries and publishers say the darnedest things about these solutions  We thought you might want to hear an unbiased review and comparison from the library community  These efforts are important for libraries and should be taken very seriously if you subscribe to any electronic journals and would like to ensure that they are preserved for future access

Some background information  LOCKSS, CLOCKSS and Portico are solutions for preserving electronic journal content  LOCKSS (Lots of Copies Keep Stuff Safe) developed by Stanford. Began in 1999, beta tested through 2002, production system developed , released April 2004  CLOCKSS (Controlled LOCKSS) based on LOCKSS s/w, started early 2006, piloting with a small number of libraries and publishers for 2 years  Portico launched by JSTOR in 2002 with funding from Mellon, became part of Ithaka Harbors, Inc. in 2004, then launched as Portico in 2005

Overview of system approaches Portico  Centralized, hosted platform  Proprietary software  No customer equipment required except browser access  Source files collected, not web presentation and PDF where available LOCKSS/CLOCKSS  Distributed, peer-to-peer platforms with error detection  Open source software  Small workstation required for LOCKSS; runs off of a CD  Specific server hardware required for CLOCKSS  Web presentation and PDF where available collected for LOCKSS; source also for CLOCKSS

Content - what’s the difference?

How the systems support perpetual access to content  Default access is always to the publisher’s existing website  Only in the event that the publisher’s website is unavailable, does access revert to the archival site

How the archival sites differ in supporting requests Portico/CLOCKSS Systems provide qualifying libraries supporting the archive with campus-wide access to archived content when specific trigger events occur, and when titles are no longer available from the publisher or other source. Trigger events include:  A publisher stops operations; or  A publisher ceases to publish a title; or  A publisher no longer offers back issues; or  Upon catastrophic and sustained failure of a publisher's delivery platform LOCKSS The institution must cache archive units (journal volumes) to their local box as they are released by the publisher Institutions often run web proxies, to allow off-campus access to subscriptions and to reduce the bandwidth cost of Web access. The LOCKSS Box integrates with these systems, intercepting requests from the community's browsers to the journals being preserved. When a request for a page from a preserved journal arrives, it is first forwarded to the publisher. If the publisher returns content, that is what the browser gets. Otherwise the browser gets the preserved copy.

And then there is CLOCKSS…  CLOCKSS differs from LOCKSS by both its structure and purpose: it is conceived as a small, responsible network providing a safety net - or dark archive - of subscription-based journals on behalf of a much broader community.  Will be made available if needed through a 3rd party TBD (e.g. Google)  Publishers and archiving libraries will have to pay to participate  Participating pilot libraries: Indiana University, New York Public Library, OCLC, Rice University, Stanford University, University of Virginia, University of Edinburgh

What content is available?  There is substantial overlap in the publishers announcing content via Portico and via LOCKSS/CLOCKSS  There is notably less overlap in the serial titles and/or issues available for preservation via the Portico and LOCKSS

Existing content comparison Number % Unique Number% Unique Publisher Titles available PorticoLOCKSS 1 Data as of 11/30/2006. Many additional titles and publishers are committed to both systems

And then there is CLOCKSS  12 publishers are participating in the CLOCKSS initiative: American Chemical Society American Medical Association American Physiological Society Blackwell Publishing Elsevier Institute of Physics Nature Publishing Group Oxford University Press SAGE Publications Springer Taylor and Francis John Wiley & Sons.

Sample displays from Audit menus Note that these do not represent the experience of the user in event of “publisher failure”

Portico’s display for available issues of a journal title  Portico has a very navigable auditing interface, comparable to end user resources

Portico’s display for an individual article  An individual article entry provides the DOI and links to the html and PDF files

Viewing the article in Portico In html  Note that internal hyperlinks are all active and links to separately maintained images are present  External links (e.g. back to table of contents) may not be active within the audit view As a PDF (where present)

LOCKSS’ display for available issues of journal titles

LOCKSS display for components from the journal volume… Each article and image component of a volume is listed An auditor must determine an appropriate ‘starting’ point - links from a table of contents screen may fail

LOCKSS display of an abstract-level screen from Oxford University Press  See a typical abstract record from the list  And the article html full text  Note internal links and separate images  And the PDF (where present)

Summary

In summary …  These are the three highest profile preservation solutions available at this time for subscription- based library content  Others may be coming  Institutions have a responsibility to participate, contributing to developing solutions for preservation of the digital cultural record just as we have done in the earlier, print-based era  There’s a solution for everyone, whether or not you have an IT staff

Considerations in selecting a solution  We currently preserve print journals, but quantity of electronic journals is much greater. The cost is still lower supporting all of these initiatives.  When looking at the options, where is the overlap with your titles?  Do faculty have interests in specific niche journals? These may be the most vulnerable.  Libraries can have tremendous influence with publishers in educating them about the need to preserve publications. LOCKSS, CLOCKSS and Portico provide an easy avenue for them to preserve their content.
