From the moment an event happens, a variety of different types of library publications about it begin to emerge. The chart above shows these types of sources on an "information timeline," starting at left when the event occurs. Sources at different points on the timeline bring different strengths and shortcomings to your research.
Click through the information timeline below to learn more about each type of source:
Timing: Days after an event
Writers: Journalists and reporters
Articles are based on: Interviews with people involved, witnesses, and sometimes expert commentators
Best for: News and facts, plus first-hand reactions and perspectives. Editorial articles are useful for opinions on issues
Issues: May contain inaccuracies since the full story isn't known yet. Often have political bias on controversial topics
Timing: 1-4 weeks after an event
Writers: Journalists and freelance authors
Articles are based on: Interviews with people involved as well as experts and authorities on the subject
Best for: News with more analysis and context, plus feature stories on people, groups, or events
Issues: May contain some inaccuracies, but overall offer deeper reporting and analysis than newspapers. Many magazines have a specific political point of view that influences their commentary
Timing: Many months later
Writers: Professors and scholars
Articles are based on: Original research that follows scholarly guidelines for that subject
Best for: Scholarly studies that provide evidence for your argument. These articles offer in-depth analysis, experimental findings, and/or criticism
Issues: Scholarly articles usually have a very specific focus. They are mostly useful once you've narrowed down your research topic and have already read broad overviews about it in encyclopedias, books, or magazines
Timing: Over a year later
Writers: Either scholars or professional authors, depending on the type of book
Based on: Original research, published studies, interviews, and the author's own knowledge
Best for: Broader overviews of a topic, including history and theory as well as analysis
Issues: Books have more space than articles to go in-depth as well as present the bigger context. They're more likely to be accurate than newspaper and magazine articles because there's been time to get the facts right. However, they're not as current as scholarly articles, and lack the firsthand perspectives of news articles
Timing: Several years later
Writers: Scholars with expertise in the encyclopedia's subject matter
Based on: Background information, plus summaries of the key findings of important books and scholarly articles on the subject
Best for: Learning basic information on a particular topic, and finding possible keywords and research questions for searching
Issues: These are a great starting point, but they lack the depth and originality to be main sources for your research. They tend to be fairly unbiased and accurate; however, they can be out of date and won't include the latest developments and findings
