In this paper we describe how the Teaching and Learning Research Programme (TLRP), an eight-year, £30 million programme charged with supporting and developing educational research in the United Kingdom has implemented and applied a DSpace as a repository for project and programme outputs including published articles, conference papers, research reports, briefings and press releases. The DSpace repository has become a major element in the user engagement strategy of the programme; the OAI (Open Archive Initiative) interface providing a basis for the development of a number of applications and services to projects and other interested groups, including search interfaces, dynamic web content, RSS feeds and other services. These have also formed the basis of collaboration and communication between the TLRP and other research programmes, indexes and resources. The TLRP is also concerned to enable collaboration between researchers and to foster individual, institutional and sector-wide research capacity. The OAI interface has been used as the basis of data visualization tools, allowing the identification of distinctive patterns of collaboration across the diverse projects of the programme, and also allows exploration of similarities and differences between education research (within and beyond the TLRP) and other disciplines.
