Lexis Nexis Academic will be releasing enhancements on August 15, 2009. The enhancements primarily impact the Easy Search form and navigation menus and (as they always say) are designed to make the database less confusing. There is an FAQ about the enhancements here. You can test the Alpha release here. I strongly recommend trying it out soon, because it looks like the main search page has changed significantly!
I particularly like the way all of the search forms are available on the homepage. The tabs to get to specific functions were often missed by students, which led me to pull out the separate search forms on our database page. Good to know the folks at LN are listening to their users!
One thing I noticed is that the Navigation menu is lost when you are taken to a specific search form, like Shepards Citations. The current search forms maintain the tabs at the top of the page, which makes it easier to jump from one search form to another.
