In this study, three years of SFX usage logs at Texas A&M University were analyzed to determine how patrons use link resolver services. The study contrasts the actions taken by users when full text is and is not available and compares public versus staff usage. The results confirmed users' preference for full-text services but also provided insights into actions taken when full text was not an option. Changes in patterns of usage over a multiyear period are shown. The data was used to redesign the SFX services menu for a more streamlined offering of services, emphasizing those that users would actually choose to use. (Contains 13 figures.)
