The two primary submission seasons are February and September. That said, a number of law reviews are open for much longer periods, and accept articles on a rolling basis.
There are two primary types of law reviews. One is the general-subject law review. This typically carries the name of the law school, such as the Washington and Lee Law Review. Many schools also have subject-specific law reviews, like the Washington and Lee Journal of Civil Rights & Social Justice.
Some useful material on law reviews include:
Law Journals Submissions and Ranking Database from Washington & Lee Law School
Allen K. Rostron and Nancy Levitt, Information for Submitting Articles to Law Reviews & Journals (SSRN Working Paper, 2020)
Robert M. Jarvis and Phyllis G. Coleman, Ranking Law Reviews by Author Prominence - Ten Years Later, 99 Law Library Journal 573 (2007).
Tracey E. George and Chris Guthrie, An Empirical Evaluation of Specialized Law Reviews, 26 Fla. St. U. L. Rev. 813 (1999).
Washington and Lee Rankings
The law library at Washington and Lee University maintains a database of law reviews with information about how often they are cited.
There is some correlation between a law school's ranking in the U.S. News and World Report rankings and in the ranking of its flagship law review.
Other Disciplines
The law library can help you develop a list of other journals from other disciplines to target with your submission. For further information, please contact Craig Eastland (c.eastland (at) northeastern.edu)
