If you haven't already done so, download the VPN software so that you can access library resources like databases, online journals, and ebooks no matter where in the world you are.
There's more to research than Orbis. Yale Law Library has its own catalog (MORRIS) and fantastic resources on human rights and international law. You can now search Orbis and MORRIS simultaneously through Quicksearch (beta). WorldCat is a mega-catalog that will show you what's available in libraries around the country, and even around the world.
You can request all sorts of things: books from Borrow Direct, books and more from Interlibrary Loan, chapters/articles from Scan & Deliver or ILL.
Don't fear the archives. Use the Finding Aid Database to figure out what's available in Yale's many special collections, or try ArchiveGrid to explore collections elsewhere.
