The National Technical Reports Library (NTRL), a service of the National Technical Information Service (NTIS), is providing free public access to its searchable online database of about 3 million federal science and technology reports. The full texts of 800,000 documents are now available to download as PDF files for free; the rest of the NTRL's reports are still on microfiche. They can be accessed as PDFs once scanned or in print for a fee. Each time one of these documents is digitized, however, NTRL will add the full-text PDF to its open repository.
