I am interested in compiling a database with the address of every operating racetrack casino establishment in the USA, for each year from 1998 to present.
This might sound like a difficult task. However, there are only 49 racetrack casinos in America at present, and they only operate in 14 states. Moreover, the industry lobby produce a report which states the number of racetrack casinos in each state for each year.
For example, from the current report, as of May 2016 the following racetrack casinos were open:
Delaware 3 Florida 8 Indiana 2 Iowa 2 Louisiana 4 Maine 1 Maryland 1 Massachusetts 1 New Mexico 5 New York 9 Ohio 7 Oklahoma 2 Pennsylvania 6 West Virginia 4
From quickly searching yellowpages.com it is pretty easy to find current racetrack casinos. For example, the four in West Virginia are:
Wheeling Island Hotel-Casino-Racetrack.
1 S Stone St, Wheeling, WV 26003.
Mountaineer Casino, Racetrack & Resort.
1420 Mountaineer CirNew Cumberland, WV 26047.
Mountaineer Casino Racetrack & Resort.
RR 2 Chester, WV 26034.
Mountaineer Casino Racetrack.
1000 Washington St, Newell, WV 26050.
I could replicate this process for the 14 states to find all 49 racetrack casinos.
My question is:
How could I repeat this process historically? I want to do this, going back in time, for each year from 1998 to present.
