The Cooperstown Chamber of Commerce (607-547-9983) offers a booklet listing things to do and places to stay. The Hall of Fame is open year-round, the Farmers’ Museum is open April through December, and Fenimore House is open May through December; joint tickets are available at a discount. The Glimmerglass Opera performs in July and August. During the summer you’ll need to make hotel reservations at least a month in advance; for popular hotels, such as the Otesaga, several months would be safer.
