Background: Lack of access to reliable health information contributes to pervasive racial and ethnic health disparities. Libraries, through their resources and programs, are sources of health information for the public. Our previous research found that individuals from diverse communities are unaware of library services and therefore underutilize this resource. Such outcomes are partially explained by the fact that these individuals do not feel welcome in their local libraries. Description: We developed a partnership with a research university, two library systems, and leaders from five communities underrepresented in biomedical research to address this gap. Our goal was to implement an intervention that increases the capacity of libraries to meet the health information needs of diverse communities. This intervention rests upon the hiring of five Community Wellness Liaisons (CWLs), one from each community, who were expected to improve the connection between diverse communities and libraries. The CWLs received library-specific training from library supervisors and health information training from a university health sciences librarian. CWLs also completed level one of the Consumer Health Information Specialization. Monthly meetings gave partners an opportunity to share information and to report on successes and challenges. The CWLs met with their community leaders to identify high-priority health concerns and with their library supervisors to plan events. The evaluation employed a mixed-methodology approach and explored partnership functioning, goal achievement, and project value. Conclusion: Prior to the COVID-19 pandemic, the CWLs reported interactions with >1700 individuals (55% with diverse community members); 25% of interactions were health related. They assigned 90 library cards (33% to diverse community members) and completed 36 programs and outreach across five health domains. One CWL shared health resources with 643 Spanish-speaking businesses over a six-month period. All stakeholders believe that the project is valuable and has the potential for lasting impact, especially regarding the perception of what libraries offer to diverse community members. One CWL said, “when you [have] worked in the community then you kind of know why a CWL is necessary because not everybody has access to [health] information,” and a leader noted that individuals from their community are becoming more “engaged in their own health.” Additionally, librarians shared that the project emphasized the need for stronger health reference and cultural awareness trainings for library staff. The lessons learned, including how to navigate multistakeholder partnerships and how to stimulate interest in library careers among underrepresented minority individuals, provide insights to others interested in using this model.
