IRs and Scholarly Communication Provide a critical component in reforming the system of scholarly communication-a component that expands access to research, reasserts control over scholarship by the academy, increases competition and reduces the monopoly power of journals, and brings economic relief and heightened relevance to the institutions and libraries that support them… Raym Crow, The Case for Institutional Repositories: A SPARC Position Paper, 2002
IRs and Scholarly Communication Institutional repositories can provide an immediate and valuable complement to the existing scholarly publishing model, while stimulating innovation in a new disaggregated publishing structure that will evolve and improve over time. Raym Crow, The Case for Institutional Repositories: A SPARC Position Paper, 2002
What is SMARTech? A set of services for the management and dissemination of the institution’s digital materials. An organizational commitment to the stewardship of these materials, long-term preservation if warranted, organization, access, distribution. Clifford A. Lynch, Institutional Repositories: Essential Infrastructure for Scholarship in the Digital Age, ARL Bimonthly Report 226, February
Populating SMARTech Began with the idea of self-submission of faculty work Evolved into library submission of digital output of campus units and… Harvesting from other repositories and… Will include library submission of faculty work and hopefully… Self-submission of faculty work
Campus Collaboration Aerospace Systems Design Laboratory Office of Information Technology OIT
Purpose of the Repositories ECE and HCC Digital Libraries (DSpace) –Course captures –Subject specific repositories –Ephemeral materials –Incomplete research materials ETDs (VT ETD-db and DSpace) –Graduate student output (now in SMARTech) ASDL (DSpace) –Knowledge management OIT –Data warehousing/storage infrastructure
The Library as Aggregator SMARTech –Repository of record for campus –Serendipitous discovery across disciplines –Long term access and dissemination –Portal to other campus repositories
Future Directions Federating Campus Repositories Federating State Repositories-GALILEO Knowledge Repository Hosted Open Access Journals
Digital Preservation 2 Southeastern Digital Preservation Networks: MetaArchive Digital Preservation Network –Part of the LoC National Digital Information Infrastructure and Preservation Program –http://www.digitalpreservation.govhttp://www.digitalpreservation.gov ASERL ETD Preservation Network
MetaArchive NDIIPP Network Auburn University Emory University Ga Tech Va Tech University of Louisville Florida State University
MetaArchive Project Summary Six partner institutions will collaborate with LoC on a three year $1.3 million effort to develop a cooperative for the preservation of digital content with a particular content focus: Southern Culture and History
Project Goals/Questions Conspectus of digital content held by the partner sites Harvested body of the most critical content to be preserved (3 terabytes) Model cooperative agreement for ongoing collaboration Distributed preservation network infrastructure based on the LOCKSS software.
LOCKSS Lots of Copies Keep Stuff Safe (Software) Stanford University Project (Open Source) In short this software will share and store data across a network and can automatically detect whether the copy at each end is valid.
LOCKSS Diagram Referenced from
Project Timeline Feb 2005: Conspectus complete May 2005: SW/HW tests complete Aug 2005: Initial archiving complete Feb 2006: Cooperative model analysis complete Aug 2006: All subsequent project harvests complete Jan 2007: All project goals complete
Preservation Network Effective digital preservation succeeds by distributing copies of content in secure, distributed locations over time This preservation network is based on a leading preservation software for distributed archiving (LOCKSS), establishing from the beginning a distributed means of replicated archives

ETD Preservation Network Now in Planning Stages – 6/2005 Goal: –Offer Collaborative Digital Preservation to Electronic Theses and Dissertations Now – Southeastern Research Libraries Later – National Network for ETD Preservation Test Participants: –ASERL | Florida State Univ. | GaTech | LOCKSS Program | Univ. of Kentucky | Univ. of Tennessee | Vanderbilt Univ. | VaTech
OAI Data Sharing – Providers and Services How the Open Archives Initiative Protocol for Metadata Harvesting (OAI- PMH)… …is making the world a nicer place to live
OAI Data Sharing – Providers and Services As a Librarian, 1.I’m very interested in the information seeking behavior of information users. 2.I’m interested in bridging the gap between user-need, and the body of external knowledge that gets expressed in the literature. In order to do this in the new digital environment, …Good Resource Discovery Tools are a must
OAI Data Sharing – Providers and Services Some Barriers to Resource Discovery within a Digital Environment: 1.“Hidden Web” was not being indexed by major search engines (Google) 1 billion – visible, 550 billion – hidden (M. Bergman 2001) 2.Limited exposure to scholarly work due to copyright restrictions Scholars typically seek high exposure to their work
OAI Data Sharing – Providers and Services As we move toward greater reliance on digital resources: 1.OAI-PMH (http://www.openarchives.org) is providing an effective low-cost solution to resource discovery.http://www.openarchives.org Many of the major information agencies have adopted OAI-PMH as a method to “expose” important information resources that reside in “hidden” or “deep” repositories
OAI Data Sharing – Providers and Services Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) Data Providers administer systems that support the OAI protocol as a means of exposing metadata A university ETD Program – Service Providers use metadata harvested via the OAI protocol as a basis for building value-added services. Networked Digital Library of Thesis and Dissertations (NDLTD) - Protocol Version 2.0 of Document Version 2004/10/12T15:31:00Z
OAI Data Sharing – Providers and Services
OAI-PMH is a relatively new service with some barriers that are yet to be negotiated: 1.Limitations on Selective Harvesting: Currently, can only select by date stamp and defined sets 2.Aggregating metadata from heterogeneous sources is challenging: By its very nature the aggregation of metadata is likely to produce unsatisfactory user experiences unless significant modification of metadata as well as targeted services are developed. -Shreeves and Kirkham, 2004 Rebel Fort on the Marrietta Road, north of the City, Atlanta, Ga., ca Civil War Treasures from the New-York Historical Society, [Digital ID, nhnycw/ad ad16008]
OAI Data Sharing – Providers and Services 1.To help overcome the barrier for creating effective aggregator services: OAI Best Practices Working Group established to address this concern. 2.In an effort to overcome the lack of a “deep Web” presence within major search services: The University of Michigan’s Oaister aggregation service is now being harvested by Yahoo: –Oaister is currently harvesting over 5 million OAI records from 480 institutions and also exposes them to Yahoo for harvest. –The result is the ability to do keyword searching using Yahoo, taking full advantage of a rich metadata record for resource discovery.
