If your project requires additional datasets, this would be a good point in the process to
repeat the above steps but with different filters. For our sample case, we would repeat
steps 3 through 8, but this time in step 4, we would choose New York instead of
Virginia.
TIP: Give each dataset you download a descriptive name so that you remember what
filters you used to create it (e.g. Transatlantic-Virginia-1701-1800.csv).
Additionally, if you’ve started with the Transatlantic database, you will need to decide
if you want gather the same set of information from the Intra-American Slave Trade
Database as well. For our sample map, we aim to include information about enslaved
people arriving from locations in the Americas in addition to those who arrived directly
from Africa, so we will repeat our two queries in the Intra-American database.
9. To switch databases, select the “Intra-American” drop-down menu at the top of
your browser window. Then select “Database.”
10.In the Intra-American Database, the search functions to filter data are exactly
the same as in the Transatlantic database, so repeat steps 3 through 8 above in
the Intra-American Database to gather parallel datasets.
11.Repeat this process for each of the geographic regions and temporal eras that
you decided to include in your map. For our sample map, this would require two
queries, each mirroring queries we already ran on the Transatlantic Database
○ Virginia, 1701-1800
○ New York, 1701-1800
By the time you finish all of your queries, you may have a number of individual
datasets. In our example, we’ll have four, two from each of the two databases. But if
you have additional criteria, you could have many more than this. You may also choose
to combine some of the files once they are downloaded—that’s what we’ll do for our
case by combining files from the two databases so that we’ll end up with two
datasets, one for New York and one for Virginia. Whatever you do, it is important to
give your files descriptive names so that you know what databases and filters they
represent.
