Looked at various issues concerning subject-based access to digital repositories
Broad perspective on ‘digital repositories’
The range and availability of digital repository sources
Cultural barriers to use of repositories in the subject community
The functionality of software tools
Advocacy materials to encourage participation of repository providers
Interactions with infrastructural shared services
Enhancing metadata quality
Embedding and reuse of resource discovery services
Improving search and browse results presentation
Service profiling for particular audiences
Listing of Engineering Repository Sources
Engineering Digital Repositories Landscape Analysis
Listing of Basic Functional Requirements for Cross Search Service
Focus Groups Reports
Setup & Maintenance Report
Shared Service Report
OAI-PMH Metadata Augmentation Report
Embedding and reuse report

What did we find out?
"We feel more strongly than ever that there are significant advantages to a disciplinary approach to electronic services supporting advanced scholarship and higher education" Stephen and Harrison (2002)
What may work for one discipline does not necessarily work well for another discipline.
Need for Subject focused services
Strongly agree 46.8%
What did we find out?
Creating subject perspectives is not always easy.
There are gap areas
Subject information environments are complex
Repositories are less important in engineering than some other subjects
The hybrid approach has limitations
Maintenance of OAI-PMH and automating reharvesting, is challenging
What else did we find out?
More content is needed
Shared services were mostly at the trial stage
We could embed a cross-search service in a VLE
Its more difficult than you might think

I think TechXtra is quite great Hi, I love your database/search facility This is really useful resource! Extra..... very professional it is a good site. I've just explored this in a bit more detail and wanted to congratulate (& thank you) for providing this service. I like TechXtra very much.
