Presented at the CONUL Conference, July 2015, Athlone, Ireland by Marta Bustillo, Tim Keefe, Trinity College Dublin. Abstract "This paper will discuss the Clarke Stained Glass Studios Collection, a collaborative project between the Library at Trinity College Dublin and the Digital Repository of Ireland. The project is digitising, cataloguing and making accessible to researchers and the wider public the business archives and the designs for stained glass windows of the Clarke Stained Glass Studios, held in the Manuscripts & Archives Research Library at Trinity College Dublin. The collection will be available both through the Digital Collections site at Trinity College Dublin, and through the Digital Repository of Ireland. The paper will explore the relevance of a research-collection based approach to digitisation of library materials; the value of a digitisation project of this kind for teachers, researchers and the general public; the challenges facing such projects; and how these can be resolved through effective collaborations with internal and external partners. The challenges include issues such as the management of the copyright and orphan works workflow; deciding on an appropriate level of description for the digitised materials; metadata mapping; and promoting the collection to the right audience. The strategies to face those challenges include collaboration with library cataloguers, subject librarians and academics; tapping on the expertise of associated projects such as the DRI; and organising research symposia to promote the digital collection internally and externally. The literature on digital collections projects in university libraries will be reviewed in order to provide an international context to our case study.
