Editing Wyomissing, Pennsylvania (section)

===20th century===
On July 2, 1906, the court issued the final decree of the incorporation of the Borough of Wyomissing. Between 1906 and the 1940s, several additional tracts of land were annexed to the borough from Spring and Cumru townships. However, 1949–1950 saw the largest annexation, with the addition of the area north of the railroad tracts known as Berkshire Heights. This drastically changed the borough map.
 
The borough evolved during this period from farmland to a large residential and commercial community. The last farmland worked in the borough was part of the Hartman Farm at the intersection of Woodland and Papermill roads. This land was sold into commercial development in the early 1990s. This includes the area now called "Woodmill Commons".

In 2002, Wyomissing merged with its smaller neighbor, Wyomissing Hills.
