We’re announcing a new layer of information in the Caselaw Access Project.

Among seven new data fields are PageRank, the all-time significance of a case based on our citation graph, and Cardinality, the number of unique words in a case. These and other fields derived from case text allow us to do things like identifying the longest court opinion ever published, or investigating how language in cases has changed over time. You can view analysis fields in the sidebar when browsing or via the API.

We want to hear about what you’ve learned and created using these fields. Let us know!

Today we’re sharing an update to Caselaw Access Project systems. This change shows one way libraries can support access to large datasets at low cost. Here’s how we did it.

This post summarizes an article recently published in the May 2020 issue of the New York University Law Review, titled An Empirical Study of Statutory Interpretation in Tax Law, available here on SSRN.

Do agencies interpret statutes using the same methodologies as courts? Have agencies and courts changed their interpretive approaches over time? And do different interpretive tools apply in different areas of law?
