ABSTRACT
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.
