How do you merge historical data from different sources?

3 Resolve the conflicts and fill the gaps

After you have identified the gaps and discrepancies, you need to resolve the conflicts and fill the gaps as much as possible. You can use various methods such as cross-checking, triangulation, corroboration, or synthesis to compare and contrast the data from different sources and find the best evidence for your research question. You can also use tools such as databases, archives, or libraries to search for additional sources that can fill the gaps or support your arguments.

4 Document and cite your sources

Finally, you need to document and cite your sources properly when you merge historical data from different sources. You should keep track of the origin, date, author, title, and location of each source you use and follow the citation style and format required by your discipline or institution. You should also acknowledge any limitations, uncertainties, or biases that may affect your data or analysis. You can use tools such as citation managers, footnotes, or bibliographies to document and cite your sources.

6 Learn from other researchers

Merging historical data from different sources is not only a technical skill but also a creative and critical one. You can learn from other researchers who have done similar or related work and see how they have merged historical data from different sources. You can read their publications, attend their presentations, or contact them directly and ask them about their methods, challenges, and insights. You can also join online communities or networks of historical researchers and exchange ideas, feedback, and support.
