The document provides guidance on writing a catalogue for research material on a given topic. It explains that the catalogue should include 10-15 primary and secondary sources totaling around 1000 words. Each source described should be around 70 words commenting on how it relates to the topic, its value, reliability, and basis for inclusion. Examples are provided of catalogue entries describing sources on the emergence of the gothic genre in American film, focusing on the works of Tim Burton. Starters are also given to help structure descriptions of sources.
