Preprint servers can enhance the access to scientific literature by bidirectional linkage from published papers (postprints) to their counterpart preprint versions. The current state of linkage is to link preprints to their corresponding postprints (peer-reviewed articles published in journals). Here, I suggest an opposite automated linkage, from postprints to preprints wherever and whenever preprints are posted on a preprint server. Such connection from paid postprint versions to free preprint versions makes sense as it removes the barriers to get access to paywalled publications freely and easily.
预印本服务器可以通过从已发表的论文（后印本）到其对应的预印本版本的双向链接来增强对科学文献的访问。目前的链接状态是将预印本链接到它们对应的后印本（发表在期刊上的经过同行评审的文章）。在这里，我建议进行相反的自动链接，即从后印本到预印本，无论何时何地只要预印本被发布到预印本服务器上。这种从付费后印本版本到免费预印本版本的连接是有意义的，因为它消除了免费和轻松获取付费出版物的障碍。
