Law search engines
Lexis, Westlaw, Juris, are the main law search engines, but require an account or payment. Free law search engines can be found at Mindworks Free Law Search. The free law movement (various countries' Legal Information Institutes) also has free law search for various countries. Unfortunately, most web searches are "fuzzy" and not precise. Most do not include character wild card or proximity search. Findlaw also has free case law as does Hieros Gamos.
