In OneSearch Manoa, search on your ancestral country/place as well as the time period that each week focuses on. For example, my ancestors are from Okinawa so for Week 1.5, I would search using these keywords: KINGDOM OKINAWA. To be more specific, we can add the time period 18TH CENTURY (or SATSUMA) to focus on pre-1778 Okinawa.
For Week 2, I would add the time period 19TH CENTURY to the above search.
When evaluating the search results, you want to ensure it covers the right time period for each question. You may need to be creative as worker's experiences/history is a relatively new area of scholarship. Workers are farmers, fishermen & fisherwomen, cooks, servants, garment makers, etc. Look for articles that examine the spheres of influence that workers will inhabit and you'll be able to pull out their experiences.
Utilize the web as a resource, as it can verify dates, changes in government, etc. For example, I did not realize that Okinawa played a vital role in the maritime trade networks between medieval East Asia and Southeast Asia, all due to its location. Also consider that colonizing governments will have useful information about your ancestral country/place. For Week 6, I searched OKINAWA COLD WAR and retrieved information about the U.S. Civil Administration of the Ryukyu Islands (USCAR), which governed Okinawa after World War II. Lower in the search is a news article that the U.S. housed nuclear weapons on Okinawa during the Cold War.
