Garb, Maggie. If You're Thinking of Living In/West Central Harlem; Abandonment Down, Refurbishment Up. The New York Times. June 21, 1998. The area [West Central Harlem], a slice of 19th-century brownstones, prewar walk-ups and small elevator buildings bounded by 122nd and 134th Streets, Morningside Park and Adam Clayton Powell Jr. Boulevard, appears on city maps as the western part of Central Harlem. Some residents call it Manhattanville, the name of the post office on 125th Street near the boulevard.
