In recent years, there has been considerable discussion about the key role which university libraries can play by engaging with their research community. As a result libraries are scoping, developing and implementing new roles and service models, especially in the relatively new area of research data. This article explores the specific challenges experienced by a traditional academic librarian at Griffith University as she moved into a new role as a data librarian. It was found that this transition needed to be underpinned by a skills development programme, a mentor/coach and a support network of specialists. The authors then outline some strategies to facilitate this type of role transition, which include investing in a range of training and staff development activities, leveraging existing core librarian capabilities and understanding the researcher perspective. The article concludes with a suggestion that several national organisations will continue to have an important role in supporting librarians as they develop new skills.
