Key Ideas - Overview
• Theorem 1: Supporters of Open Access should support NDLTD.
• Theorem 2: 5S can guide us to better support of Open Access.
![Page 6: 1 Symposium: Open Access to Information Panel 3: BDTD (Biblioteca Digital de Teses e Dissertações) 25 August 2006, Brasilia NDLTD: From Local to National.](https://reader036.fdocuments.in/reader036/viewer/2022062421/56649e415503460f94b3365d/html5/thumbnails/6.jpg)

Theorem 1: Supporters of Open Access should support NDLTD - 1
• DLs will lead to enormous benefit at all levels, from personal to global.
• An IR is a type of DL, in the middle of the levels (requiring support from below, and providing support for above levels).
• Having a DL at every university (i.e., IR) greatly encourages Open Access.
![Page 7: 1 Symposium: Open Access to Information Panel 3: BDTD (Biblioteca Digital de Teses e Dissertações) 25 August 2006, Brasilia NDLTD: From Local to National.](https://reader036.fdocuments.in/reader036/viewer/2022062421/56649e415503460f94b3365d/html5/thumbnails/7.jpg)
7
Theorem 1: Supporters of Open Access should support NDLTD - 2
• The easiest way to launch an IR at a university is with ETDs.
• NDLTD is the lead world organization promoting ETD activities.
• NDLTD’s goals are all in support of Open Access and IRs.
![Page 8: 1 Symposium: Open Access to Information Panel 3: BDTD (Biblioteca Digital de Teses e Dissertações) 25 August 2006, Brasilia NDLTD: From Local to National.](https://reader036.fdocuments.in/reader036/viewer/2022062421/56649e415503460f94b3365d/html5/thumbnails/8.jpg)

Theorem 2: 5S can guide us to better support of Open Access - 1
• 5S helps us think formally about Open Access, hence clearly, hence to find focus.
• 5S helps us design and build DLs, hence IRs.
• Societies– Individuals: members of institution, discipline– Social influence can promote DL (re)use.– Economic and political and social issues lead us
to a distributed architecture.
![Page 9: 1 Symposium: Open Access to Information Panel 3: BDTD (Biblioteca Digital de Teses e Dissertações) 25 August 2006, Brasilia NDLTD: From Local to National.](https://reader036.fdocuments.in/reader036/viewer/2022062421/56649e415503460f94b3365d/html5/thumbnails/9.jpg)

Theorem 2: 5S can guide us to better support of Open Access - 2
• Distributed infrastructure + services lead us to harvesting (vs. federation, gathering).
• 5S helps make harvesting a success:– Streams of content flow from individuals.– Structures: ETD-ms, (browsing) classification– Spaces: indexes, interfaces– Scenarios: submission, workflow, harvesting– Societies (see above)
• More collaboration (social networks)• Prestige is more widely spread.• Access if more open

Institutional Repositories - 2
• “A university-based institutional repository is a set of services that a university offers to the members of its community for the management and dissemination of digital materials created by the institution and its community members. It is most essentially an organizational commitment to the stewardship of these digital materials, including long-term preservation where appropriate, as well as organization and access or distribution.”

UK Report of Aug. 2006
• EVALUATION OF OPTIONS FOR A UK ELECTRONIC THESIS SERVICE
• Study report edited by Alma Swan• Key Perspectives Ltd & UCL Library Services• EThOS project (Electronic Theses Online
Service) - commissioned to develop a model for a workable, sustainable and acceptable national service for the provision of open access to electronic doctoral theses.

EThoS: Issues
• Electronic thesis provision status in the UK and the reasons for its slow development
• Drivers for change in the provision of e-theses• The administrative and academic contexts in which
a national UK e-thesis service would need to operate
• Constraints that might apply, or which have applied until the present
• Architectures and service models for e-thesis provision
• Technical standards• IPR and other rights issues• Business models
![Page 21: 1 Symposium: Open Access to Information Panel 3: BDTD (Biblioteca Digital de Teses e Dissertações) 25 August 2006, Brasilia NDLTD: From Local to National.](https://reader036.fdocuments.in/reader036/viewer/2022062421/56649e415503460f94b3365d/html5/thumbnails/21.jpg)

Elements of an ETD Initiative - 1• The hub: the central focus of the service may offer multiple
resources and subservices or, at the other end of the scale, may be a simple resource discovery service: The hub may point at theses located in host institutions or it may contain the full-text of theses itself
• Submission procedure: the simplicity of and requirements for this can vary
• Metadata structure and format: the required metadata formats can vary from very simple Dublin Core with few elements to a deeply descriptive specially developed metadata scheme with many elements
• Metadata dissemination: services vary in the extent to which they disseminate thesis metadata – some only expose it themselves, while others disseminate it via multiple discovery services and routes
• Accepted file formats: some services accept multiple file formats, some few and some just one
![Page 22: 1 Symposium: Open Access to Information Panel 3: BDTD (Biblioteca Digital de Teses e Dissertações) 25 August 2006, Brasilia NDLTD: From Local to National.](https://reader036.fdocuments.in/reader036/viewer/2022062421/56649e415503460f94b3365d/html5/thumbnails/22.jpg)
22
Elements of an ETD Initiative - 2
• Digitisation: a digitisation service may be part of the offering. If it is, it may be on demand or there may be a mass retrodigitisation programme on offer
• Thesis level: services may offer only doctoral theses or may extend their coverage to masters theses and even undergraduate dissertations
• Copyright and IPR: services may incorporate advice and practical help on rights issues
• Plagiarism: services may offer a plagiarism detection scheme
• Business model: under this heading fall issues such as: whether theses are offered on a pure Open Access basis or whether the access is paid for; whether royalties are paid to authors; how digitisation costs are covered and so forth

Why ETD? Short Answer
• For Students:– Gain knowledge and skills for the Information Age– Richer communication (digital information, multimedia, …)
• For Universities: – Easy way to enter the digital library field and benefit
thereby
• For the World: – Global digital library – large, useful, many services
• General:– Save time and money– Increased visibility for all associated with research results

Union catalog: OCLC
• OCLC will expand OAI data provider on TDs.
• Is getting data from WorldCat (so, from many sites!).
• Will harvest from all others who contact them.
• Need DC and either ETD-MS or MARC.
• Has a set for ETDs.

VTLS
• VTLS offers its free VALET system to manage ETDs at institutions, building upon Fedora, as well as VTLS software.
• VTLS runs a service provider atop the Union Catalog. It supports multilingual access through the interface, to metadata.

LOCKSS
• Lots of copies keep stuff safe
• Stanford (Vicky Reich)
• Initial focus on lower levels
• Initial content: journals
• Emory (Martin Halbert)– Help deploy and adapt– Help apply in other contexts, e.g., ETDs
• Experiments, studies of Int’l ETD service– Humboldt, PUC Rio, U. Cape Town, VT, …

Full-text Services
• Running since Sept 2005: Scirus• In beta test: Google Scholar• Challenges:
– Broadening the coverage since OAI use has not spread as widely as we would like
– Understanding use, throughout life cycle– Data and DL services quality problems– Inconsistency in way to get from metadata to the full-
text file(s)– Cross-language information retrieval

As data, information, and knowledge play increasingly central roles … digital library
research should focus on:
• Increasing the scope and scale of information resources and services;
• Employing context at the individual, community, and societal levels to improve performance;
• Developing algorithms and strategies for transforming data into actionable information;
• Demonstrating the integration of information spaces into everyday life; and
• Improving availability, accessibility, and, thereby, productivity.
![Page 64: 1 Symposium: Open Access to Information Panel 3: BDTD (Biblioteca Digital de Teses e Dissertações) 25 August 2006, Brasilia NDLTD: From Local to National.](https://reader036.fdocuments.in/reader036/viewer/2022062421/56649e415503460f94b3365d/html5/thumbnails/64.jpg)
64
An appropriate infrastructure program will provide sustainability of digital knowledge
resources among five dimensions:
• Acquisition of new information resources;• Effective access mechanisms that span
media type, mode, and language;• Facilities to leverage the utilization of
humankind’s knowledge resources;• Assured stewardship over humanity’s
scholarly and cultural legacy; and• Efficient and accountable management
of systems, services, and resources.
