Until October 31, 2015, you can come and try out Gale Virtual Reference Library in the Library of Book History, Library and Information Science. The multidisciplinary database includes encyclopedias and other professional information resources in various special fields (Arts, Biography, Business, Education, Environment, General Reference, History, Information and Publishing, Law, Literature, Multicultural Studies, Nation and World, Religion, Science, Social Science, Technology and Library Science).
Earlier these resources, which are in fact e-books, could be studied only in a printed format but now there is an opportunity to try and get to know this database.
