Telephone, faximile, documents, photocopies, checking out books, computer-printouts and other electronic media are available depending on users' demand. Majority of users are those who connects NSO's statistical database via telephone circuits or public networks. Statistical data are served on users' own expense basis. These expenses are arising from using computers, writing programs and other related services. NSO is running statistical libraries.
Librarians answer for the users on the spot or refer to the related divisions or agencies.
In addition to consulting the statistical data, faximile, photocopy and mailing services are available.
