This is a great place for digital information for South Carolina users and contains reputable sites in association with the SC State Library.

Make sure to check out Teen Book Cloud for 24/7 access to some great eBooks.

Some of the great databases for research include:

Bloom's Literature
Britannica School
Credo Reference
Explora EBSCO
Gale in Context (Biography and Opposing Viewpoints)
History Reference Center
Literary Reference Center
NoveList Plus
Points of View Reference Center
Science Reference Center
StudySC (great for research on people in our state)
Writer's Reference Center

There are many others.  Also check out Learning Express Library for information on future careers, computer skills, and test taking strategies for college admissions exams such as the SAT.  You will need to create a special login to use this site.  I highly recommend doing so.
