The Hugh & Hazel Darling Law Library at UCLA
has published an Online guide entitled Legal Research: Beyond LexisNexis & Westlaw
They write
This Guide describes a wide range of online legal research resources. It covers primary law, government resources, research guides, reference sources, forms, and legal news.
It is of course US centric but does look well presented and researched and probably worthy of a bookmark
