Publishing work in conference proceedings is common in the forensic science community. JFS welcomes submissions including material that has been published in a proceedings abstract. However, the submission should provide a substantial enhancement of methods, analysis, and conclusions over the published conference proceedings and must conform to the requirements described under each manuscript category. The EIC and/or Associate Editor make the final decision on what constitutes "substantial enhancement." Authors must provide details of the conference proceedings in the cover letter, including a relevant citation. Failure to do so may be a reason for rejection. Author(s) must obtain all the necessary permissions to re-use published material, if appropriate.
