You should know about the Law Library of Congress. It's an abosolute treasure. Their website allows you to ask obscure research questions. And get answers. For free.
A few weeks ago I had to find a Lagos (Nigeria) State Statute. It was the 2007 Lagos State Law to Provide Protection Against Domestic Violence and Connected Purposes. And most law libraries don't have Nigerian statutes — much less the statutes of the various Nigerian states. I sent an email to the "Ask a Librarian" link on the website for the Law Library of Congress, which found the law for me and sent me a PDF of 40 Lagos State of Nigeria Official Gazette, No. 53, A187-201 (Jul. 30, 2007). It took a couple of weeks, but that's ok — I got what I needed.
If you have a sticky research question, remember to test out the stunning resources of the Law Library of Congress. And if you're in Washington DC, be sure to pay them a visit.
