On October 26, 1998, the Legislative Yuan abolished the current publishing law, which had been in effect since 1930. This paper discusses mainly publishing laws and regulations and the history of the legal deposit system, as well as the current publishing law related to legal deposit regulations, the national library's capabilities under the library law concerning new legal deposit regulations, and suggestions regarding the future establishment of legal deposit regulations. It is hoped that the R.O.C. will establish a reasonable and mutually beneficial legal deposit system that is both service-and culture-oriented.
