Question

List the source of modern history

Answer 1

A primary source of information for historians is the official records of the British administration.              The British kept written records of every key instruction, meeting, transaction, investigation, plan, policy decision and agreement. They attached record rooms with all the important administrative institutions.

The British built specialized institutions like museums and archives to preserve important documents.  
Historians gather important information about the provincial administrative system from the reports, memos, notings and letters preserved in the 19th century in the archives and record rooms across India.

For effective administration, the British carried out a number of surveys in the early 19thcentury.
