NASA CASI Closes, but STI Services and Products Continue

The STI Program announces the closure of the two offsite, contractor-operated NASA Center for AeroSpace Information (CASI) facilities, effective for operational work on December 15, 2014. CASI served the Agency for several decades by collecting, organizing, disseminating, and preserving NASA’s STI. In recent years the move from print-based to digital-based collection and storage of content has diminished the need for an offsite processing facility. We thank CASI for their dedicated and hard work.

Although CASI is closing, all STI services and products are currently transitioning to contract services at the NASA Langley Research Center by Dec. 8, 2014. As such, customers will continue to have access to the same products and services to which they have been accustomed.

The new STI address is:
NASA STI Program
STI Support Services
Mail Stop 148
NASA Langley Research Center
Hampton, VA 23681-2199

What is the NASA STI Program?

The NASA Scientific and Technical Information (STI) Program was established to support the objectives of NASA’s missions and research. It is dedicated to the advancement of aeronautics and space science. This program is essential to help NASA avoid duplication of research by sharing information and to ensure that the U.S. maintains its preeminence in aerospace-related industries and education. The NASA STI Program acquires, processes, archives, announces, and disseminates NASA STI and acquires worldwide STI of critical importance to NASA and the Nation.

The STI Program and its support contract services are critical components in the worldwide activity of scientific and technical aerospace research and development. Collected from U.S. and international sources, STI is organized according to content prior to being added to the NTRS Registered, which is a world-class collection of STI that includes over 4 million bibliographic records and a growing number of full-text documents. A public interface is available through the NASA Technical Reports Server (NTRS).
