What to do when designing a repository for an institution that doesn’t already have a predefined structure or taxonomy by which to organize or make ‘browsable’ your collections? Conference attendees who come from complex institutions without clearly set “Departments” will be interested to hear how Providence St Joseph Health (PSJH) created an organizational structure and taxonomy during the implementation of their Digital Commons IR. By considering existing classification schemes (LC and NLM), internal naming practices, and consulting small stakeholder focus groups PSJH is making their publications easily browsable by both internal and potential external users.
