The major legal encyclopedias include extensive information on ADR methodologies and how they are used to resolve particular types of disputes. The links below are to these encyclopedias in Westlaw.
The American Law Reports (ALR) series is like a legal encyclopedia. Each ALR article, or "annotation," discusses a legal topic or principle in great detail and provides a multi-jurisdictional survey of relevant case law.
ALR annotations are generally more narrow in scope than articles in legal encyclopedias; however, they cover their respective topics in much more depth.
ALR is available through Westlaw and LexisNexis. The HLSL collection also has the ALR in print format (although the set is not currently being updated, so its most recent annotations will not be available in that form).
Below is a list of selected ALR annotations discussing ADR topics. The links provided are to the ALR in Westlaw.
