Seeing the Big Picture: Sustaining Success in Liaison Services.

While the liaison program at the Tompkins-McCaw Library for the Health Sciences has existed for more than 15 years, it has yet to be fully evaluated. This article seeks to evaluate the scope and impact of the program at a broad level using quantitative and qualitative data. Descriptive statistics to summarize liaison activity were collected for the fiscal years 2012-2016. In addition, liaisons and users were surveyed to gain insight into the effectiveness and the perception of the program. Program statistics show that users' engagement with liaisons is high and growing. Qualitative data reveals that while better methods are needed to assess the extent of the program's impact, users appreciate the value that liaisons bring by supporting the educational and research missions of various programs.
