Reference Universe
Why was Reference Universe created?
Most libraries are challenged with maximizing the use of their printed reference materials which is made up primarily of subject encyclopedias. About 90% of all reference questions get answered by subject encyclodias. With this in mind, Reference Universe was designed to solve this challenge. Reference Universe serves as a bridge for reference librarians and their patrons, between maximizing the use of their local print reference holdings, as well as accessing newer, online reference databases.
