Because arbitrations are private, they often are not published. One of the central challenges facing the researcher is lack of accessibility of arbitral decisions. However, some arbitral decisions and rules from various arbitral bodies are available via Westlaw. See below. Often, rules and awards are also available via the arbitral bodies' website.
Westlaw's International Arbitration Materials provides access to cases, awards, rules, conventions, legislation, model laws, and more for practicing U.S. lawyers.
