“The U.S. Government Printing Office has been informed by National Aeronautics and Space Administration (NASA) that users of certain electronic NASA documents are not to share documents that are marked publicly available in the NASA Technical Reports Server (NTRS) until further notice. The documents cannot be shared with non-U.S. citizens. NASA staff members are reviewing all documents that were previously marked “publicly available” and were loaded on the NTRS to determine if the documents have an approved NF-1676 (Document Availability Authorization) with export control signature and approval. Robert Lightfoot, NASA Associate Administrator, ordered that the NTRS be taken down and the following message was approved for release by John Hall, Export Control and Interagency Liaison: “The NASA technical reports server will be unavailable for public access while the agency conducts a review of the site’s content to ensure that it does not contain technical information that is subject to U.S. export control laws and regulations and that the appropriate reviews were performed. The site will return to service when the review is complete. We apologize for any inconvenience this may cause.” During this time, PURLs that GPO has created for the electronic versions of NASA Technical Reports found in cataloging records accessed through the Catalog of U.S. Government Publications (CGP) may not link to the documents that the catalog record describes. GPO has been asked to suspend any activity related to making these documents available if they have not been reviewed. When NASA makes full content on NTRS available once again, the database will be redesigned and have enhanced features for access.”
