Currency of Information
(This section is adapted from part 4 of Duke University's Guide to Library Research)
Information about an event will appear over time in different types of resources. This time line indicates the minimum amount of time after an event takes places or an idea is developed that information about it filters into various types of media.
Currency is particularly important when your research:
Involves current events
Focuses on topics that require current data and theory
Focuses on a particular historical era or event
For example: I am taking a course on the history of music in the 20th century
We were assigned an interesting article about Jazz.
I am from New York and have always been interested in its history.
I did some searching for 'Jazz' in the Encyclopedia of American Studies.
I looked through some articles about the history of Jazz in Ebsco Megafile.
