This case study shows how the reference librarians at Murray State University use Pinterest as an added component in reference services. Statistics were collected in an attempt to monitor the number of items shared with the number of people who actively follow each board. This study will help interested reference librarians gain an understanding of how this social media site can be used to promote online resources, both those owned by the institution and those freely available on the internet. It will also serve as an example of how reference librarians can build a reference library within the confines of social media.
