The Indonesian language, also called Bahasa Indonesia, lacks much of a presence on the Internet. The report made by the World Wide Web Technology Survey shows that the percentage of websites using the Indonesian language is only 0.5 percent. This chapter describes the issues related to Indonesian lexicography in the era of Internet. It refers to the lexicography of the Indonesian language, as the national language of the Republic of Indonesia. The chapter analyses the core issues in the development of Indonesian lexicography, includes the issues on dictionary awareness, standardization, corpora, and technology. It offers some perspectives and ideas for the development of Indonesian lexicography in the future. In 2016, the work on establishing the existence of Indonesian lexicography in the era of the Internet was also done by Oxford University Press of the University of Oxford with its Oxford Indonesian Living Dictionary, which is a part of the project called Oxford Global Languages (OGL).
