The Hook

Have you heard of the Negro Motorist Green Book? Published annually from 1936 to 1966, it was a travel guide for Black Americans -- a directory of hotels, restaurants, barber shops, and gas stations where a Black traveler could expect to be served, or at least not turned away. Victor Hugo Green, a Harlem postal worker, compiled it. He sold it for seventy-five cents. It was the size of a passport.

The Green Book has been rediscovered in recent years -- there was a movie, exhibits, digital archives. But no one has done what we do here: overlay every Green Book listing in America with every documented Negro Leagues game location from the same period. The result is a map of where teams could stop and where they could not. The cities with no listings go dark.

Between 1936 and 1948, Negro Leagues teams played in 13 league cities across the eastern half of the United States. For each of those cities, we asked a simple question: how many Green Book listings existed within walking distance of the ballpark? Using the NYPL's geocoded 1947 edition (1,051 listings, CC0), the answer ranged from 24 (Washington, D.C.) to zero. Nine of the thirteen league cities had zero listings within a mile of the park. The zero cities are the ones that matter most.

The radius search uses two thresholds: 1 mile (walking distance from the ballpark) and 5 miles (a short cab ride, if a cab would take you). The 1-mile count is the primary metric. A city with zero listings within 1 mile is a dark city -- a place where the team arrived and there was nothing listed in the book.

The swing. Negro Leagues teams did not play home-and-away series like major league clubs. They barnstormed -- long road trips through multiple cities, playing a game every day, sometimes two. The schedule was improvised. The route was shaped by where they could find a ballpark, an opponent, and an audience. What it was not shaped by was where they could find a safe place to eat or sleep.
The safety score. We compute a composite score for each city using four weighted components derived from the NYPL Green Book data: listings within 1 mile of the ballpark (40%), listings within 5 miles (20%), presence of a hotel or tourist home listing (25%), and category diversity (15%). A score of 0.50 or above suggests baseline accessibility. Below 0.30 is a city where the Green Book offered almost nothing within reach. Note: the NYPL geocoding pipeline has known accuracy limitations, particularly for Northeast cities. See the methodology section.

The Conclusion.

League-Wide Trend, 1936--1948

Across thirteen seasons and seven regions, the safety score barely moved. In 1936, the league-wide average was 0.38. By 1948 -- the year the color line cracked -- it was 0.39. The Green Book grew thicker every year, but not in the cities where Negro Leagues teams played. The places with the ballparks were not the places with the listings. The infrastructure of segregation and the infrastructure of Black baseball occupied the same geography but different economies. The teams drove through the dark. For thirteen years, the dark did not get any lighter.

01
The Pope Hotel

On Wylie Avenue in the Hill District, the Pope Hotel was a fixture of Black Pittsburgh. When the Homestead Grays came home from a road trip, visiting players from the opposing team stayed here. It was 0.8 miles from Forbes Field. Not far, unless you didn't know it was there.

02
The Crawford Grill

Named for the Pittsburgh Crawfords, or the Crawfords named for it -- the history is disputed. Gus Greenlee owned both. After games, players from both sides ate here. Jazz musicians came through. It was the center of Black Pittsburgh nightlife from 1933 to 1951. Fourteen blocks from the ballpark.

03
The Loendi Club

An elite Black social club founded in 1897. Members included doctors, lawyers, and the occasional Negro Leagues owner. The club's basketball team was nationally known before the Crawfords or Grays. By 1941, it was a Green Book listing and a place where Black travelers knew they would be welcomed.

The last edition.

The Green Book published its final edition in 1966, two years after the Civil Rights Act. Victor Hugo Green died in 1960. He never saw the law change. The guide he built was a workaround -- a map of where the system had cracks. It was not a solution. It was survival infrastructure, published annually, seventy-five cents a copy.

"There will be a day sometime in the near future when this guide will not have to be published. That is when we as a race will have equal opportunities and privileges in the United States. It will be a great day for us to suspend this publication, for then we can go wherever we please, and without embarrassment."
-- Victor Hugo Green, 1948
