National Library System has been playing a leading role in archiving national publication as well as in moving libraries nation wide forward. Now our government plans to merge Taiwan branch Library of National Central Library and National Taichung Library into National Library System. Also, under planning is the construction of a new branch at the southern part of Taiwan. In view of such major projects to be implemented, a fresh need arises with regard to making possible innovative changes to national library's organization structure, operational model and its future outlook. Upon request from government authorities, this research paper is to present a preliminary study concerning key factors of the aforementioned fundamental aspects. This research employs comparative methods and interviews to conduct this explorative study, with the aim that the findings resulted would be beneficial to further studies to come.
