ASME publishes over 2,000 conference papers per year. ASME Papers – if published as a technical paper, they are not published as part of a conference proceeding.
IMECE (International Mechanical Engineering Congress and Exposition) – ASME sponsors this conference, but does not publish a conference proceedings. Some papers presented at IMECE are published by the individual ASME technical divisions as conference proceedings.
Proceedings of the ASME... series – conference papers not published as a technical paper are published in a conference proceeding in this series.
Some technical papers and some proceedings are also later published in ASME journals. Index to Place of Publication of ASME Papers 1950-1977 and also Index to Place of Publication of ASME Papers 1978-1988 are two print indexes that will allow researchers to check and see where specific ASME papers may have been reprinted.
You can also search ASMEpapers (for 2002-present) from within the ASME website on their conference proceedings page
Looking for a year not covered by any of the above options? I suggest you try searching by author/title in a database of published articles such as Compendex or Google Scholar. Or, look for later publications by the same author - they often cite their own earlier publications in the list of references.
