LII has recently undertaken a major updating and revamping of its topical section. Building on the topical material that was originally developed for its "Law about..." pages, LII has launched Wex, a collaboratively-created, freely available, public-access legal dictionary and encyclopedia.
How does Wex differ from the "Law about..." section? Wex will continue to provide reliable, accessible legal resources at no charge. By adopting a collaborative approach, LII plans to involve a larger pool of experts and bring together more limited efforts into a "unified, rich, community-based resource." See the Wex:FAQ for further information.
Wex is an example of a wiki, of which Wikipedia is probably the most well-known example. However, in the interest of generating higher-quality material in the short term, LII will keep the authoring pool selective for now. If you would like to volunteer, see Editorial contributions.
