The peer-review system in academic publishing is highly stretched to near crisis levels. Several methods, including the introduction of peer-review metrics or indexes, have been proposed to incentivize voluntary uptake of peer-review. However, these are largely based on the prolificacy of peer-review completion, but do not adequately reflect rigor or quality of the review reports. I argue that peer-review credit should also be based on the latter. As such, peer-review reports should be made citable, and these citations might constitute at least part of a comprehensive peer-review metric.
