The information timeline is one way for us to think about how different kinds of publications provide different perspectives on a topic based on when they are published. The cycle begins when information on a topic or event appears in social media and newscasts and continues through more comprehensive analysis and coverage in peer-reviewed scholarship and books.
Review this short tutorial to better understand how the timeline works. The tutorial will open in a new window.
You can think about the NU Library’s resources as sources of information that fall along the lines of an information spectrum. The information spectrum chart provides a helpful way to identify and evaluate the sources and information you will use for research.
Below, the Information Spectrum Chart lists various kinds of information sources and the various places we can find these information sources. Notice that the information sources listed on the left are all found on the Internet and are produced very quickly. The information listed on the right is found in electronic and print formats and includes scholarly information, which cannot always be found freely on the Internet but can be found in the library.

Journals typically have other experts in the field review articles prior to publication. In a blind peer-review, reviewers know the author's name. In a double-blind peer-review, neither the author(s) nor the reviewers know the identities of the others. To find the level of peer-review of a particular journal, you usually need to look at the editorial statement of that journal.
