The UCD Digital Library began as a niche project focused on digitizing select special collections materials. Early criteria for selection included available technology, preservation needs, existing digitization projects, user demand, and metadata availability. Over time, drivers like centenary initiatives, strategic university objectives, and increasing digital technologies pushed the Digital Library towards mainstreaming and expanding its stakeholder base to include additional repositories, researchers, teachers, and schools. While growing functionality created new opportunities, managing expectations of what digitization and services involve remained important. The Digital Library transitioned from its initial niche role to increased engagement both within and outside the university.
