Reports

What they are: Documents created by particular organizations, reporting on particular issues.

What they give you: Basic facts about an issue, and analysis of that issue.

Note: Some reports are neutral, but not all of them are. If a report argues for one side of a controversial issue, it's up to you to evaluate the argument and respond to it.

How to spot them:

• They are usually published online, often in PDF format.
• They are usually created by a particular organization, such as a company, a non-profit, an NGO, or a think tank.
• Sometimes they have the same publication info as an ebook, but the "publisher" is just the organization that created the report.
• They usually have high-quality graphic design, with lots of images.
• They support the agendas (and the biases) of the organizations that create them.
