Main Page - Wex Wex is an ambitious effort to construct a collaboratively-created, public-access law dictionary and encyclopedia. It is sponsored and hosted by the Legal Information Institute at the Cornell Law School (http://www.lawschool.cornell.edu/). Much of the material that appears in Wex was originally developed for the LII's "Law about..." pages, to which Wex is the successor.
