The Collin County Archives at Plano Public Library houses a variety of maps of Plano spanning from 1880 to 2020.

These maps show how much the area has changed over time, and Plano has changed a lot! Founded in the mid-1800s, the population of Plano was just over 550 people in 1880. Today, Plano has a population of over 285,000. 

The archives have a number of maps beyond those of Plano. Included in the collection are maps of Collin County from its beginning in 1846, maps of where the Peters’ Colony was located, other Texas counties, many state maps and older atlases.
