We’ve talked here in the past about searching HeinOnline (see here and here). It takes some getting used to if you’re coming from Google, Westlaw or Lexis, but can be very valuable to legal researchers. Hein has continued to improve its search experience and now they have added faceted searching which can help you refine your search results. Once you run a search in the Law Journal Library you will now see a side bar (see below) on the left that will show you facets by which you can refine your search. Facets include document type, dates, subjects, titles, country published and state published. I particularly like the date facet as I can quickly see what articles appear in HeinOnline that I would not find in Westlaw or LexisNexis. For a quick demo check out this online tutorial.
