Luther College expanded its majors and introduced two new interdisciplinary programs: Identity Studies and Global Health. The collections used to support these courses needed to be reviewed and appropriately developed to meet the needs of future users. Both have an emphasis on diversity and equity, and the collection also needed to reflect these values. Our project served to develop the collection in four key ways: analyzing the existing collection and presenting a report to the Luther library team, creating a list of recommended titles to purchase, creating research guides, and creating collection development guidelines and recommendations for subject liaisons.
