I Research Any Topic

Missing: books, libraries, lectures, free-form conversation with real people.

There is a writer I follow on Twitter @dart_adams who has deep expertise in 80s and 90s rap and video games. An ongoing issue he constantly encounters is faulty information on Wikipedia which is the go-to source for journalists and others writers. Dart will dig up the relevant paper archive (online if available, at the Boston Public Library if not) to correct the faulty record.
