Real property auction maps, also known as "farm maps", are sheets or pamphlets created by auctioneers sometimes containing maps, birds-eye views, and or descriptions of land for sale. The majority of the Library's collections that show property for sale in Brooklyn were published between the late 19th and mid 20th century and document the gradual transformation of the borough's southern and eastern neighborhoods from a collection of sparsely populated "suburban" areas into a dense urban space tightly connected by a interconnected grid of streets, avenues, and parkways. The easiest way to locate this map type in the research catalog is by using the keyword search term "Brooklyn real property auction."
