Disclaimer: I know this service is available to all Maryland residents, but I’m not sure how people from out of state are handled.
Maryland’s public libraries have a great service called Ask Us Now where you can chat with a librarian about research questions. It’s a good idea to have done some preliminary reading first — librarians are underpaid and often unappreciated, so wasting their time when a google search would suffice is rather unkind — but for harder or more specialized research questions, this service is a real boon.
The quality of service may vary somewhat, but in general you’ll get good advice on useful sources online, or, if you happen to live in Maryland, in print.
