This article is the culmination of my three year project with the Massachusetts regions as it pertains to their delivery operations. The paper presents important aspects and issues related to the merging of six regional library delivery services in a single statewide system that serves more than 550 libraries, that together circulate more than 15 million items annually throughout the Commonwealth of Massachusetts. The purpose of marrying the six distinct systems was to reduce redundancies and incorporate innovative features to improve library processing efficiency. Most libraries are members of one of nine separate shared integrated library systems. The paper covers the background, objectives, benefits, issues, lessons learned, and a successful request for proposal procurement process for this complex project.
