So what are eSources, anyway, and how could they help you? eSources are resources with quality content. They differ from other information found online--anyone can put up a web page on a subject, with or without understanding it, but the information in our eSources is written and vetted by experts in appropriate fields. Better yet, much of the content in eSources is pulled from books, like encyclopedias, and moved online so it's available to more than one person at a time. eSources can also include full-text newspaper, magazine, and journal articles, or answers on topics ranging from auto repair to test preparation.
