Conclusion from the pre-print paper: > We have shown that, within the boundaries of our corpus, there are no significant differences in aggregate between pre-prints and their corresponding final published versions. In addition, the vast majority of pre-prints (90% - 95%) are published by the open access pre-print service first and later by a commercial publisher. Given the fact of flat or even shrinking library, college, and university budgets, our findings provide empirical indicators that should inform discussions about commercial publishers’ value proposition in scholarly communication and have the potential to influence higher education and academic and research libraries’ economic decisions regarding access to scholarly publications.
