The Mellon Centre, which is a branch of the Northern Ireland Library System, based in Belfast, still has an extensive collection of information available. The librarians there are not researchers, but they can provide a wealth of valuable information on how and where to find the information on emigration to America and elsewhere. Persons wishing to track information should plan to spend some time there searching through the stacks which are readily available. There are also family collections in files. Visitors might also be lucky enough to be there when others are searching for similar information. Networking is always a good idea.
