We live in a society where information comes at us from every direction: top down, bottom up, and sideways from our friends and colleagues. Thinking about the type of information you are looking for helps you narrow the playing field.
You will get the right kind of information you need faster.
Information doesn't just "happen" or "exist" on its own. It is produced by people and then disseminated, either through traditional (e.g., mainstream and scholarly publishers) or non-traditional (e.g., self-publishers, Internet) channels. Each has its merits, based on the kind of information you need.
Knowing what type of source you need or are currently using will tell you how the information has come to exist, so you can answer the following:
Source Type | Examples |
Primary A primary source is a first person account by someone who experienced or witnessed an event. This original document has not been previously published or interpreted by anyone else. |
|
Secondary A secondary source is one step removed from the primary original source. The author is reexamining, interpreting and forming conclusions based on the information that is conveyed in the primary source. |
|
Tertiary A tertiary source is further removed from primary source. It leads the researcher to a secondary source, rather than to the primary source. |
