LexisNexis turned on the link to the Academic beta during the ACRL conference. I stopped by their booth and confirmed that the new interface is going live at the end of June. I haven't had a lot of time to kick the beta's tires yet. The new interface looks similar to Westlaw's Campus Research. Iris has posted notes from the LN update lunch held during ACRL.
I met with a Lexis Nexis rep last month and played around with the interface a little. I love that fact that they have subject headings now on their articles, but I’m skeptical how the “one box to rule them all” search will work out for students.
