In this exercise, learners are required to distinguish the information belong to "primary sources" or "secondary sources". Primary information source are anything created at the time when the incident/event happened. They were created with the intention to record the incident/event. It could be a document, manuscript, autobiography, a recording, a diary, an artifact, and so on. Secondary information source is anything (e.g., documents, records, artifacts, objects, and so on) that discuss, relates, or refers another piece of information existing elsewhere.
In this slide, it introduces different type of resource was created with a particular kind of purpose: to transmit facts, to interpret the findings, to put forward a viewpoint, to let fellow workers know some important idea, and so on.
In this video, a team of students arrive the university library and meet the Reference Librarian at a discussion room. The Reference Librarian firstly recaps the concepts of the AAOCC. Then, she mentions the additional criteria for evaluating the primary and secondary sources!
There's lots of Engineering information on the Web.
Some ask you to pay money; your library probably already subscribes to many good sources.
As you develop into a professional engineer, you will learn to go beyond general web pages or web docs & become a more sophisticated engineering information user and creator.
In this video, it introduces different engineering information (characteristics & purposes).
