AIChE Annual Meeting Conference Proceedings and AIChE Spring Meeting Conference Proceedings are available in both online and CD-ROM formats (for 2006 up through about a year ago) and they contain all papers presented at the conference.
AIChE Symposium Series – is a series of books that contain the “best” of the AIChE conference presentations.
Conference presentations are often published as articles in one of the AIChE journals.
In recent years, AIChE has begun cooperating with other societies in sponsoring joint Specialty Meetings. The availability of these proceedings varies with each conference.
To verify where a given conference paper may have been published, use Compendex or SciFinder. The AIChE website does not currently offer an online searchable index of all their publications but conference proceedings for each year can be browsed from the Publications page on the AIChE website.
