A Look Back on HeinOnline's "Topics"

In the more than 20 years of HeinOnline's growth, our content has expanded beyond law reviews to include scholarly journals and government documents that apply to nearly any discipline. In recent years, this multidisciplinary content has become essential to a variety of different academic and applied fields. 

Using a combination of human curation along with natural language processing and machine learning, we've extracted thousands of research concepts from this multidisciplinary content. You may have seen them throughout HeinOnline under the name Topics.

About PathFinder

As we grow our multidisciplinary content, we continue to enhance methods for its discovery, including ways to more easily utilize our thousands of research concepts in browsing and searching. 

PathFinder is a suite of browse and search tools for subject-specific research, powered by a multi-level subject taxonomy that has been organized from the ground up based on our initial list of 1,500 "topics." Now called Subjects, these granular research concepts have been categorized into increasingly broad levels.
