Journal-level metrics aim to measure the influence of a journal. There are many journal-level metrics based on different methods/tools of calculation and datasets. However Professor Kathy Bowrey from Faculty of Law, UNSW, states that "metrics remain insufficiently developed to provide a credible and robust proxy to assess law journal quality".
With that in mind, journal citation data should not be used in isolation to evaluate the prestige and suitability of a journal, especially in Law.
Journal rating lists have been created to supplement the rankings from Journal Citation Reports and Scopus Journals. The rating lists from Excellence in Research for Australia (ERA) are most known.
