The National Technical Information Service is the central source for the public sale of Government-sponsored research, development, and engineering reports and other analyses prepared by Federal agencies, their contractors, and grantees. Current summaries of these reports are published by NTIS in over 30 newsletters, catalogs, and journals. The system used to organize these summaries permits NTIS to create a number of useful information products from a single machine-readable data file. The presentation covers the range of products made available and some of the techniques that are used and that may be applicable to other publishers.
