Research Made Easy

HeinOnline has implemented research tools and concepts to help both novice and experienced researchers make the most of its content. Using natural language processing and machine learning, HeinOnline’s research tools aim to vastly improve the discoverability of relevant content. Below is a brief breakdown of all the tools available in this database.

Venn Diagram – NEW!

With the new Venn Diagram, researchers can visualize the results yield of various keywords to better refine their searches. This feature saves valuable time and effort, eliminating the need to continuously switch databases and/or edit a search. Although the original search targeted the combination of these three terms, users can also view the results of other combinations by selecting the Clear button and hovering over the additional options.

The More Like This button allows users to find similar articles based on the current article they are viewing. Use this feature to discover “interesting words” within the article, as determined by an algorithm, and view a list of similar articles based on the words. Find the More Like This button on the upper right-hand side of an article page.

ScholarCheck is a series of tools which help researchers quickly locate related material throughout the interface. HeinOnline’s most powerful tool yet, ScholarCheck:

Metrics counted for each author include:

  • Number of times cited by articles (total)
