Looked at various issues concerning subject-based access to digital repositories
Broad perspective on ‘digital repositories’
![Page 8: Perx and TechXtra](https://reader035.fdocuments.us/reader035/viewer/2022062312/5558abbad8b42a2a738b53a0/html5/thumbnails/8.jpg)
Information landscape
![Page 9: Perx and TechXtra](https://reader035.fdocuments.us/reader035/viewer/2022062312/5558abbad8b42a2a738b53a0/html5/thumbnails/9.jpg)
We investigated..
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 Maintenance issues 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

We produced…
Listing of Engineering Repository Sources Engineering Digital Repositories Landscape Analysis Listing of
Basic Functional Requirements for Cross Search Service
Focus Groups Reports Advocacy Materials 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– Agree 46.8%– Strongly agree 46.8%
![Page 15: Perx and TechXtra](https://reader035.fdocuments.us/reader035/viewer/2022062312/5558abbad8b42a2a738b53a0/html5/thumbnails/15.jpg)
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
![Page 16: Perx and TechXtra](https://reader035.fdocuments.us/reader035/viewer/2022062312/5558abbad8b42a2a738b53a0/html5/thumbnails/16.jpg)
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

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.
