To the genealogists: Trackers of family history have been drawn to the Allen County Public Library's Genealogy Center (near the ballpark, of course) since 1961, but now its references, online connections and expert guidance draw as many as 70,000 folks a year, some holing up for days. "The only collection that's free and open to the public that's larger than ours," says Witcher, "is the Family History Library in Salt Lake City."
