The VitalSource Resource

When I was in school, I remember using World Book Encyclopedias when I wanted to do a quick browse on a topic. Over the years, with encycopedias moving online, this habit has moved to a quick Wikipedia search and review. Wikipedia is often the first or second web hit when using an online search engine. Accoring to Alexa Internet, Inc. and SimilarWeb (companies that track commercial web traffic data and analytics), Wikipedia was the fifth-most used website in 2016.
