How the “Most-Cited Authors by Subject” Ranking Is Calculated (Comprehensive)

Overview

This ranking identifies the most-cited authors within twenty-five major legal subject areas across all institutions and disciplines represented in HeinOnline’s Law Journal Library. For each subject, citation and usage data are drawn exclusively from articles written by the author that contain one or more PathFinder Subjects mapped to the relevant subject category. HeinOnline’s ScholarRank formula is applied separately for each subject to produce a top 100 list of influential authors.

Eligibility

All authors with at least one article in HeinOnline’s Law Journal Library qualify for inclusion in this ranking. For each subject, only the author’s articles that contain PathFinder Subjects mapped to that subject category are counted. Each subject list presents the top 100 qualifying authors for that subject.

Metrics Used

Each subject-specific ranking is based on the following five metrics, drawn from subject-filtered author article data in HeinOnline:

1. Cited by Articles (0 to 5 Years)
   Counts the number of times subject-mapped articles written by the author have been cited by other articles in HeinOnline within the past five years. Citation style sources include the Bluebook, Prince’s Dictionary of Legal Abbreviations, and the Cardiff Index to Legal Abbreviations.
2. Cited by Articles (5+ Years)
   Counts the number of times subject-mapped articles written by the author have been cited by other articles in HeinOnline more than five years after publication. Citation style sources include the Bluebook, Prince’s Dictionary of Legal Abbreviations, and the Cardiff Index to Legal Abbreviations.
3. h5-index
   Measures the productivity and citation impact of the author’s subject-related publications over the most recent five complete calendar years. The index reflects the number of articles (h) written within the subject during that period that have been cited at least h times.
4. h-index
   Measures the overall productivity and citation influence of the author’s full body of subject-aligned work. It is based on the author’s most cited publications within the subject and the number of citations those articles have received.
5. Accessed (Past 12 Months)
   Measures relevancy and recency by counting the total number of times subject-mapped articles written by the author have been accessed by HeinOnline users in the past twelve months. An article counts as accessed when it is clicked from search results, navigated to directly, or retrieved through the citation navigator.

Calculation Method

Z-scores are calculated for each of the five metrics within each subject. These five Z-scores are averaged to generate the author’s overall subject score. The final average score is placed into the standard competition ranking to determine the top 100 authors for each subject.

Formula

Z-score Calculation:
Zx = (x – µ) / σ

Average Z-score:
Zµ = (Z1 + Z2 + Z3 + Z4 + Z5) / 5

Final ScholarRank:
Zµ, ranked using standard competition rules within each subject.

Update and Refresh Schedule

Each subject ranking is refreshed with every monthly HeinOnline content release, at which point all citations are fully recounted. This ensures that the standings remain current as new scholarship is published and cited.
