University of Pennsylvania Law Review

Founded in 1852 as the American Law Register, the University of Pennsylvania Law Review is the nation’s oldest law review. In the 2019-2020 academic year, the Law Review will publish its 168th volume. The Law Review has both a professional and an educational mission. It serves the legal profession, the bench, the bar, and the academy by providing a forum for the publication of original legal research of the highest quality. We accept and scrutinize approximately 2,000 written submissions annually to select approximately eighteen articles in each volume. We also ensure uniformity in the citation of authority in legal scholarship and court documents by cooperating with our peer organizations at Columbia, Harvard, and Yale in the maintenance of The Bluebook: A Uniform System of Citation. The Twentieth Edition of The Bluebook was published on May 1, 2015. The Law Review also affords Associate Editors two valuable educational experiences. First, we provide training in the performance of all the editorial and administrative tasks associated with the publication of a professional legal journal. Second, we assist each of our members in preparing an original work of scholarship suitable for professional publication. Associate Editors are encouraged to write their student comments on a subject of particular interest to them, and up to twelve comments will be selected for publication.

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.
