Horbach, S. P. J. M., & Halffman, W. (2018). The changing forms and expectations of peer review. Research Integrity and Peer Review, 3(1), 8. doi:10.1186/s41073-018-0051-5 (open access)
In addition to a systematisation of the current variety in peer review, the paper also explains the considerations that have gone into innovations such as post-publication peer review, open peer review, or statistics scanners. Two further papers are in preparation, one on the distribution of peer review practices and one on their ability to prevent retractions.
