Gale Virtual Reference Library Star
Gale Virtual Reference Library is a database of encyclopedias, almanacs, 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).

StarAccess to this premium web-based content is one of the privileges of holding an OSL (Ocean State Libraries) or Lincoln Public Library Card.
