The Online Search Service provides fee-based access to a collection of approximately 600 databases through the DIALOG service. This service supplements our large collection of subscription-based databases, which are available to library users free of charge. In order to see a list of library databases available at no user cost go to Library Databases A-Z . All DIALOG searches are conducted by User Services librarians. You will be notified when your search is available for pickup at the Reference Desk on the First Floor. Please call either (615) 898-2817 ext. 3 or (615) 898-2549 for more information.
