The publication of a newsletter is one way that the Penghu Living Museum works to raise public awareness and concern. Through dissemination of museum news, local residents understand local cultural work, regain living memory, and realize the meaning of this museum. The aims of this study are, on the one hand, to understand the impact of publications on museums and, on the other hand, to elucidate the impact of text structure on the cognition of local life. In particular, the following questions are addressed. How does the Penghu Living Museum re-construct the position and role of this publication? Who decides the themes of this publication? Who writes the content? How do its core values affect local life? In a diversity of aspects, there are corresponding and reciprocal relationships between the museum and its promotional materials. This paper is roughly divided into three sections: (1) The analysis of the preparatory process of the Penghu Living Museum, (2) construction of the role and position of the museum’s newsletter, and (3) exploration of the relevance of encoding and decoding of the museum’s newsletter. From its evolution from a folded leaflet to its current small booklet form, there have been changes in the persons responsible for the newsletter’s publication and in the editorial content. The content has become more integrated with local people, events and places and this newsletter is no longer just a part of the museum’s operating policy. In Stuart Hall's encoding and decoding theory, the editor of the museum’s newsletter is not only the coordinator and the person with the most direct control, but is also the person who guides the overall content and style. The decoding results, in terms of opposition of readers, can serve as a reference for improving publications.
