Abstract:

[Purposes] This paper aims to introduce the publishing and spreading situation of virtual issues in scientific journals and summarize the organizing strategies, thereby advancing the reform of the knowledge service mode of scientific journals. [Methods] Through the information search method, we investigated the subject classification, topic selection, number of papers, collection period, forms and channels for promotion, monographic paper downloads, and cited frequencies of virtual issues from international academic publishers and Chinese scientific journals' cluster platforms. [Findings] Virtual issues covered a wide range of disciplines, and the downloads and citation frequency of the papers were higher than those of the non-virtual issue papers published at the same time. Virtual issue topics included academic hot spots, high-impact authors, high-impact scientific institutions, important funding projects, and so on. Virtual issues were mainly published through the internet. The publishing forms of virtual issues were divided into the graphic type and the rich-media type. In the future, big data, cloud computing, virtual reality, artificial intelligence, and new think tank of scientific journals will promote the rapid development of virtual issues. [Conclusions] Virtual issues can conduct in-depth knowledge mining and provide systematic knowledge services for the whole process of scientific research according to the needs of users and combined with the characteristics of journals. Virtual issue is a beneficial exploration for the integrated publication and precise knowledge service of scientific journals.
