The pressure to distinguish high quality from lower quality law journals is intensifying. To contribute to this debate, citation-based and peer review-based ranking of law journals are paralleled in the paper, using qualitative and quantitative analysis. It is found that all law journals that are considered as journals of the highest quality by legal experts are also ranked highly in Web of Science (WoS) and that 40% of the law journals categorised as ‘internationally leading’ by the peers are not listed in WoS. This paper explores what the editors of some of the internationally leading law journals that are not listed in the WoS think about applying to be listed in it. The paper offers data to support the contention that legal scholarship is characterised by regionalism in academic publishing and citation patterns. It is submitted that there is no perfect indicator of quality, and that no evaluation system will ever convince every legal scholar in the world of its value. WoS could be adopted as a rigorous and internationally recognised index for law journals only if it were aligned more closely with the Leiden Manifesto.
