The Engineering Library's collection of Technical Reports consists of over 1.5 million reports on fiche, dating back to the early 1960s. The collection is shelved in Columbia's ReCAP offsite library shelving facility.
About 1/3 of the collection was received through the National Depository Program, which includes NASA, NACA, DOE, ERDA, and AEC reports. The rest of the collection is acquired by subscription called SRIM (Selected Research in Microform) from NTIS. SRIM, a service provided by the National Technical Information Service (NTIS), distributes U.S. and foreign government reports on a wide variety of subjects including Engineering, Physics, Agriculture, Medicine, Ecology, and Transportation. Effective FY 1997, DOE and NASA stopped issuing reports on microfiche. They are available electronically on the DOE website and the NASA website.
