You may want to carry out research for your writing - to supply some period colouring, or historical detail, or simply to prevent howlers like having Romans eat tomatoes (in fact they were first cultivated by Aztecs and Incas and came to Europe from the New World).
The research I did for a non-fiction work, Curiosities from the Cabinet: Objects and Voices from Britain's Museums, involved finding out all I could about each of the 36 objects in the book, then slimming this down into short introductions to longer contributions from interviewees about each one.
