On the occasion of the 20th anniversary of the Vietnam Museum of Ethnology’s establishment, the Museum & Anthropology Review publishes a special issue with double number of pages. It is an add-up issue that includes issue No. 3 and issue No. 4 of the fiscal year 2015. Its articles share the opinions of Vietnamese scholars about museum theories and museum practices that have been applied at the Vietnam Museum of Ethnology. Such professional activities as research, object collecting, conservation, organizing exhibitions and educational programs, communication, and audiovisual documentation etc. are reviewed in order to comprehensively evaluate the progress of the Vietnam Museum of Ethnology through its 20 years of development. This progress is evidenced by the Museum’s permanent exhibitions including Ethnic Peoples in Việt Nam, Architectural Garden, Southeast Asian Cultures, Indonesian Glass Paintings, A Glimpse into Asia, and Around the World as well as nearly a hundred of temporary exhibitions such as Thai Textiles in the Mekong Sub-region: Continuity and Changes, Life in Hanoi under the Subsidy Economy (1975-1986), Mekong Stories – Challenges and Dreams, Route 9: Opportunities and Challenges, Pains and Hopes – 20 Years of HIV/AIDS in Vietnam, Living in the Sacraments – Contemporary Christian Culture in Vietnam, Stories in the City: Voices of Communities etc. Difficulties and challenges to the Museum’s activities are also pointed out in the articles and some solutions are put forward in order to improve the quality of the Museum so as to attract more visitors.
