Types of sources
- As research is created and disseminated, it moves from being a primary source → → toward being → → a tertiary source.
- The earlier in the process (and closer to the actual science being done) the more likely you are dealing with a primary sources.
- When you start to research a topic (before you do any science), you go the opposite direction ← ←. You may start with a tertiary source, like Wikipedia or library database and move toward the original work or primary research.
