The Great Courses:
The Great Courses Library Collection is the leading global media brand for lifelong learning and personal enrichment, with hundreds of courses spanning thousands of in-depth video lectures.
Gale Virtual Reference Library is a database of encyclopedias and specialized reference sources for multidisciplinary research. These reference materials once were accessible only in the library, but now you can access them online from the library or remotely 24/7. Because each library creates its own eBook collection, the content you see may vary if you use the database at different libraries (your school, your public library, or your office).
