数字出版环境下,书后索引数字化是书后索引的发展趋势。数字化书后索引将会超过纸质书后索引的比重,但是在一定时期内,纸质书后索引依然是书后索引的基础工作。本研究认为,需要分层次有序推进书后索引工作的数字化发展,并对此提出了确定优先编制的书后索引类型、发展书后索引产业链、重视书后索引研究和实践的国际交流三种策略。 Digital publishing environment, the index after the book is the index after the development trend of the book. After indexing digital book will exceed the proportion of paper book index, but in a certain period of time, paper book index is still the basis of the book after the index. This study argues that it is necessary to promote the digitized development of indexing work after the book hierarchically and orderly, and put forward three strategies for determining the priority indexing type, developing the bookindustry indexing chain, and focusing on the research and practice of indexing afterwards.
