This collection defines, explains, and analyzes secondary sources and accompanies our Primary Sources collection.

This collection is a part of the Smithsonian Libraries and Archives Information Literacy series. In an age where there are myriad sources of information, unending news coverage, and a vast, often unregulated digital world, it can be confusing to determine which research sources are trustworthy and reliable. This digital series is dedicated to helping students and educators think critically about how they identify, find, evaluate, and use information effectively.
