If the proceedings you are looking for is not available online, try a search in the U-M Library Catalog, using "ASME" plus the series abbreviation and the volume number; e.g.:
ASME HTD 83
Alternately to using the catalog, or if catalog search doesn't work, you can use the ASME Proceedings Call Number Spreadsheet to look up the call number for the proceeding by title words and/or volume number (but note that this spreadsheet will not be able to tell you if it is checked out or not).
Finding IEEE Proceedings

Finding MRS Proceedings
For a proceeding published from 1998 to the present, check to see if there is a digital version in the Materials Research Society Online Symposia Proceedings.
For a proceeding published prior to 1998, or for which there is no electronic version, first try a search in the U-M Library Catalog, using "Materials Research Society" and the volume number; e.g.:
Materials Research Society 588
If that doesn't work, try a title words search with the title of the Symposium; e.g.:
Advanced Cementitious Systems
Finding SPIE Proceedings
For a proceeding published from 1990 to the present, check to see if there is a digital version in the SPIE Digital Library.
For proceedings published prior to 1990, or for which there is no electronic version, first try a search in the U-M Library Catalog, using 'SPIE' and the volume number; e.g.:
SPIE 3886
If that doesn't work, try a title words search with the title of the Conference, but without the roman number number; e.g.:
Lasers in Dentistry
not
Lasers in Dentistry VI
