Within the context of Taiwan's socio-cultural development, this paper examines the predicaments and challenges for compilation of local gazetteers over the past two decades (1999-2019) and reflects on how local gazetteers progressed from tradition to innovation and revitalization. Reviewing the 40-year culturalization in Taiwan (1977-2019) reveals that public participation in local studies has gradually become the mainstream, particularly with the emergence of participatory construction of local knowledge in the past 20 years. Contrary to the traditional practice of local gazetteers compiled mainly by experts and scholars, the bottom-up and diverse approaches to local knowledge construction, promoted by both the government and the public since the 1990s, has become the current convention. Compilation of local gazetteers in the past two decades encountered predicaments including limited budget, weak motivation of local participants, constraints under the Government Procurement Act, deficient administrative resources for local units, and challenges of web search engine. Future development of local gazetteers must cater for demands of the Internet era and needs of the users. While encouraging public participation in collaborative writing and introduction of more local information, the framework and contents of local gazetteers should still be handled by professional teams to ensure comprehensiveness and rigor. Moreover, digital platforms should be constructed for the public to access and update information. Local gazetteers should become public-oriented, with increasing social responsibility under popular demands and with professional compilers leading public participation. Convenience brought by digital technology should facilitate the collection and enhance extensive application of the local knowledge. Nevertheless, it is easier to establish a website than to maintain it; hence, there should be due and thorough assessment on long-term maintenance before establishing a digital platform or knowledge base.
