We recently obtained a subscription to SAE Mobilus online, which includes SAE technical papers from 1980 to the present.
We also have other, earlier SAE technical papers in hardcopy or microfiche, as follows:
In addition, SAE J-series ground vehicle standards are located in the SAE Handbook. The print set (2005) is located in Uris Library Reference, TL 151 .S67. A CD dated 2009 is in the Engineering Librarian's office. Contact firstname.lastname@example.org for an email of a particular standard.
1946-2001 - in the Library Annex.
2002-onwards - issued as part of conference proceedings volumes, such as ASME International Mechanical Engineering Conference and Exposition. Use Google Scholar and Compendex to find publication numbers, then search the Library Catalog (a.k.a. Classic Catalog) for the individual conferences.
Another tool is Seventy-Seven Year Index: Technical Papers 1880-1956, Uris Reference TJ1 .A517. Also here is an index to 1957-1970.
Papers not held at Cornell may be requested through document delivery.
