Identify what is relevant for an investigation by asking, 'who?', 'what?', 'when?', or 'where?'. While these are lower-order questions, they are a first step in identifying relevant sources.
Primary sources include Sacred Scripture and authoritative religious documents. Original writings from other authors and statistics from reputable surveys are also primary sources.
Secondary sources include articles that explain or comment on primary sources such as Newspaper reports, websites, some texts, etc.
Locating information requires some understanding of the research focus and some idea of where suitable sources can be found. Relevant information needs to be identified, recorded, processed and organised in a way that both facilitate the research process and achieve the intended purpose of the research. The techniques used tp locate, identify, record, process and organise relevant information will create a trail of evidence that serves to justify what has been found and to show that the work is your own.
