• Resumen

  • This study evaluates and compares how accurately three legal citators (Shepards, KeyCite, and BCite) identify negative treatment of case law, based on a review of 357 citing relationships that at least one citator labeled as negative. In this sample, Shepard's and KeyCite missed or mislabeled about one-third of negative citing relationships, while BCite missed or mislabeled over two-thirds. The citators' relative performance is less clear when examining the most serious citator errors, examples of which can be found in all three citators.
