Lauren Austin, a legal knowledge consultant at Mallesons has started up a blog dedicated to legal research tips and tricks for "junior (and not-so-junior) lawyers, law graduates and law students".

The really interesting aspect of her blog is that she has created a Google Books custom search across a set of legal research materials.  At present it's heavy on US content, but Austin plans to add more Australian content over time.  

You can find the Google Books search here:
