Map collections and resources: Road

This library guide will introduce you to Stanford Libraries map collections, services, and related resources.

Road maps


Branner Library Map Collections contain thousands of road maps and road atlases covering the United States from the 1920s to the present. The maps are primarily a part of two large donations from the AAA of Northern California, Nevada, and Utah and the Robert C. Berlo Road and Street Map Collection. The following guide will enable you to locate these maps and also enable you to utilize other resources for learning about and finding road maps.


Road maps were regularly produced from the early days of the automobile by oil companies to encourage people to explore the country by car. These were often given away for free at gas stations. Maps were issued year after year showing the growth of the road network throughout the United States. 

The Road Map Collectors Association has compiled a Master Catalog of American Oil Companies That Issued Road Maps. 

Road maps were often issued without easy to read dates making it hard to tell when a map was out of date. Two resources are available to help one decipher the codes typically used by the map makers:

The David Smollar Map Collection

In 2019, David Smollar donated a large portion of his map collection to Stanford University Libraries. In general, the over 2,000 maps demonstrate the evolution of road maps from the early 1900s to modern day, especially for the state of California. Within this evolution, David is particularly interested in map censorship during World War II and collected many maps depicting this practice. 

You can browse the David Smollar Map Collection using SearchWorks, our online library catalog.

As part of his collecting endeavors, David wrote the following essay on domestic map censorship during WWII:

Robert C. Berlo Map Collection

Robert (Bob) C. Berlo started collecting road maps as a child. In Maps: What I Collect and Why, he writes:

"My interest in maps began after the Second World War, when the end of gas rationing allowed my father to take us on family jaunts from our San Francisco home nearly every weekend.  I began my own collection with the maps and road atlases my father and uncle used for our trip to a 1952 family reunion in Boston.  As a native Californian, I took paved and multi-lane roads for granted, so was fascinated to see unpaved major roads in the Plains.  This sparked my interest in the history of highways and towns.  I eventually collected a road map of every one of the seventeen Western states for every year from 1925 to the present."

Over time, his collection grew to over 13,000 maps covering the whole United States. In 2012, Bob donated his collection to Stanford University and is now viewable in our online catalog, SearchWorks.
