It is an ongoing process, but I think Law Search has reached Beta status, just, and has thus been promoted to the sidebar.
The custom specialist search, via Google co-op, prioritises results from listed sites, but includes general search results. The listed sites aim to cover freely available resources for statute, case law, commentary, reports, blogs and other resources for UK, particularly English, law. Subscription based and limited access sites are not included.
Nick Holmes has set up specialist custom search engines for particular areas (eg, Blawgs, Legislation, Case law). I would be very interested in any comments people might have on the relative utility of a ‘general’ law custom search and the ‘focused’ custom searches. I use both, but my search needs only cover certain areas, so I cannot be clear about effectiveness. If it turns out that delimited specialist searches are more useful, I’ll give this CSE a rethink.
