Top 100 Journals Comparison Across Multiple Legal Research Databases

Content News, Exploring HeinOnline, Law Journal Library

One of the most commonly asked questions addressed to the HeinOnline support team is "What does HeinOnline have compared to other legal research databases?" Until recently, no known sources contained information about what each database has in terms of depth of content and coverage. Thus, this analysis was performed on database content for the top 100 law journals for six major legal research databases: HeinOnline, Westlaw*, LexisNexis Academic, JSTOR, Gale LegalTrac, and EBSCO Legal Collection. The results of the study are discussed in detail below.

Methodology

Washington and Lee University's Law Journal Ranking Project was used to determine the list of the top 100 law journals, according to the Ranking Project's combined score. Journal rankings on this list are determined by this ranking methodology. Next, lists were compiled of both indexing and full-text coverage for these 100 journals for HeinOnline, Westlaw, LexisNexis Academic, JSTOR, Gale LegalTrac, and EBSCO Legal Collection. Because HeinOnline's coverage for all but one of the top 100 journals was found to be the most comprehensive, we located the most-cited article within each journal and compared the availability of these important articles among all six databases.

Sources

Lists of journal coverage for databases other than HeinOnline were located, and indexing and full-text coverage information for the top 100 journals was then extracted. These lists were obtained from the following sources:

Cumulative Number of Indexed Volumes Available

The total number of available indexed volumes was counted for each database. For instance, HeinOnline has a total of 6,421 volumes which contain indexed material, and most of these volumes also contain the full text. Most databases will have a greater number of indexed volumes than full text volumes due to embargoes requested by individual publishers.

Number of Most-Cited Articles Available in Full Text

The most-cited article in each journal was determined using HeinOnline. The following chart shows how many of these articles are available in full text within each database.

Compared to HeinOnline, the other five databases had the following percentages of full text content:

Summary of Findings

1. HeinOnline

  • Westlaw* has 51% of the full text volumes and 51% of the indexed volumes
  • Lexis has 39% of the full text volumes and 39% of the indexed volumes
  • JSTOR has 25% of the full text volumes and 25% of the indexed volumes
  • Gale LegalTrac has 5% of the full text volumes and 52% of the indexed volumes

*For this study, an official, Westlaw-issued list of content and coverage was not found to be available. In addition to the list from Lancaster University, information was obtained from Cassidy Cataloguing. The coverage listed by Lancaster University may not be complete in many instances, as articles were often individually selected from within the content periods listed. In the interest of erring on the side of caution and because it was not possible to verify actual coverage, the coverage listed by Lancaster University was used, regardless of volume completeness. Therefore, coverage listed for Westlaw may be inflated. Please refer to the first Excel spreadsheet, column AM, for more information.
