Publishing Policy The editors' policy on division preprints is as follows: Publication of a preprint or extended abstract in an ACS division meeting preprint book in either print or electronic format does not preclude consideration for publication of a full paper in an ACS journal, provided that it includes significant new information and data beyond what was in the preprint or extended abstract. It may well preclude publication of a communication.  Also see the complete ACS Journal Editors' Policy on Preprints. Copyright © American Chemical Society
