The Town of Westfield was incorporated on March 4, 1903, replacing Westfield Township. The name of the town is derived from its location in the western, undeveloped fields of the Elizabethtown tract. According to the United States Census Bureau, the town had a total area of 6.743 square miles (17.463 km2), including 6.719 square miles (17.401 km2) of land and 0.024 square miles (0.062 km2) of water (0.36%). Unincorporated communities, localities and place names located partially or completely within the township include Germantown and Tamaques Reservation Mill. Six municipalities border the town of Westfield: Mountainside to the north, Springfield Township to the northeast, Garwood and Cranford to the east, Clark to the southeast, and Scotch Plains to the west and southwest. The upper reaches of the Rahway River Parkway run through the township along tributaries of the Rahway River. The Westfield Memorial Library was founded in 1873 as the "Every Saturday Book Club" and has evolved over the past century into the Westfield Memorial Library of today. The Library is located in a large, modern, Williamsburg-style building at 550 East Broad Street. The library's collection consists of over 250,000 books, two dozen public computers, a wide array of multimedia options, a large youth services area with a vivid mural depicting Westfield history, and multiple tables and carrels for studying. The library offers classes for adults and children, storytimes for children, and computer instruction. Westfield's downtown features many local and national stores and several landmarks that were shown and used in the NBC network television show "Ed" such as the Rialto Theater. There are over 40 restaurants and casual dining establishments throughout the downtown. Downtown is located mostly north of the Westfield train station. The downtown area has a mix of independent stores and boutiques as well as national stores. Over one-third of the retailers and restaurants have existed for 25 years or more. Downtown Westfield, with over 200 retail establishments and 400 commercial enterprises, is a regional destination in New Jersey.
