Who doesn't like something new? New cars, new clothes, new experiences.
New or current information is desirable too. Current information is often what our research questions demand. But sometimes older information sources may contribute as much if not more value to research as newer information sources.
The quality of our research is related to how carefully we analyze the currency of our information sources.
Knowing when the information source was last published or updated helps us determine the usefulness of the information presented.
