Finding technical reports can be hard - don't hesitate to ask for help.



Technical Reports

Technical reports are scholarly papers issued by government labs, agencies, and universities. 

Reports on microfiche are kept at the Library Annex. However, we have equipment that can directly make a PDF file from a microfiche record. You can request a scanned copy from our interlibrary loan Be sure to specify exactly which report you need.

To locate microfiche, do a title search by the series name in the library catalog (for example, AD-microfom, PB-microform, NACA-microform). A few records may also link to URLs with full text.

You can also contact the Engineering Library with questions by email,

For certain "lost" technical reports from the 1940s and 1950s, there is a paper published by the University of Nebraska here. Many of these reports are not available from the NTIS or other sources but methods for obtaining them via the Library of Congress can be found within that paper.

Locating Technical Reports at the Engineering Library 

NTIS: the National Technical Information Service has provided access to government-funded scientific, technical, engineering, and business related reports. Reports are filed under their report number, such as PB- (from NTIS), N, NASA (from NASA), AD- (from Department of Defence), and USGS (from U.S. Geological Survey). See the chart for a more detailed list.For declassified documents, check 'Declassified Documents Reference System'. Some of our reports back as far as 1942. More complete holdings start in 1978, when Cornell began subscribing as a depository library for NTIS reports. 

Technical Report Servers at Universities

  • Networked Computer Science Technical Reference Library (NCSTRL) is a collection of CS technical reports on distributed servers from 157 institutions. Most of the institutions are Ph.D.-granting universities in the field of computer science. Cornell computer science reports dating back more than 30 years are included.
  • TRAIL - - pre-1975 federal technical reports; information at, developed by University of Washington.
  • Unified Computer Science TR Index. This is an automatically created index of technical reports available by anonymous FTP all over the Internet. Coverage is much broader than the CS-TR collection above.

Technical Reports from Government Sources 

While only some of these sites have the full-text documents, all are excellent for purposes of verification.
