CLOSER Discovery is the UK's most comprehensive research tool for longitudinal population studies (LPS). DDI-Lifecycle is used to document questionnaire, question, dataset and variable metadata from 11 (and counting) leading UK studies. CLOSER Discovery is powered by the Colectica software stack including a customised Colectica Portal which sits on top of Colectica Repository, and provides access to item level metadata through display as web pages. Since the launch in 2017, the CLOSER Discovery portal has had only minor visual updates within the bounds of the underlying software. In the latest update, launched in September 2023, we have worked with Colectica to update the Portal software, enabling the implementation of the design created by Bravand, a digital design and build company with experience of complex websites. CLOSER Discovery has been redesigned using detailed feedback from one-to-one interviews with users, focussing on the home, search and explore pages. The poster will detail the new design features and the feedback it is based on.
