this article introduces several of the more significant service delivery innovations and their resulting accomplishments instigated by dongguan library (thereafter abbreviated as dgl) in recent years. the textual exposition of this paper is based on a case study of dgl by this author about its user-centered vision, mission, immediate objectives and the exhibited service performance within a contextual environment of collegial support from its professional   peers. after a five-year period of intensive efforts on such focused professional development and practice, dgl has completed its information service mapping and information delivery for the entire municipality of dongguan on a 7-day and twenty-four-hour (7/24) basis. this singular feast of accomplishment seems to suggest the moral that any significant development of scale of a municipal library has to be in keeping pace closely with the progress of the society at large in general and with the changing information demands of its local clientele in particular.
