A pleasant, almost ethereal cerebral dysrhythmia occurs when you proceed from the hot, mean, dirty streets of downtown Miami to the main library. The lights glow softly, the air feels cool and clean, the people seem sedate and serene. Deep in the northwest corner of the second floor lies the Florida Room, an inner sanctum, a placid place devoted to Miami, to Florida, to realities other than what waits for you outside. Here you'll find The Florida of the Inca, Florida in the Making, and Florida: Land of Change. By loading up some microfilm and spinning through old copies of the Miami Herald you'll be transported to 1937, 1954, 1968, or any time you want. The room holds county perspectives and state profiles. Florida's statutes, maps and plats, old phone directories (from back when they listed your place of employment along with your name, address, and number). References: animals, architecture, water, land, linguistics, treasures, wars, plantations, folksongs, folklore, real estate, foods, plants -- all of it Florida. And if you want to get out of town, step over to the genealogy section and peruse History of Cuyahoga County, Ohio (1879), Tyrrell Cemeteries, North Carolina 1732-1984, Early East Tennessee Tax Lists. Or to get the perfect perspective, grab Victor Rainbolt's The Town that Climate Built. The ancient Miami-PR tome is undated, but a computer-bar code search suggests it was likely published in 1925. An excerpt: "Here may be found the out-of-the-way things that excite the imagination."
