Yes, everything looks fresh and new when you go to HeinOnline now. The new interface has a nice clean look to it, though it is extremely blue. I'm not sure how much they've improved the actual search experience, though. I had some trouble finding an advanced search page, and I'm not sure you can do one search across all the databases. Let's try to use it over the summer before passing judgment.
You can access HeinOnline from off-campus by using the Pitt vpn to get into the University Library System's digital library, where Heinonline is on the "databases A-Z" list.
