The NDEI policy is to present only data which has been published or “in press” following peer review. However, the NDEI recognizes that important information in a rapidly progressing field, critical to a more thorough understanding of the field, is frequently presented at national or international conferences with publication to take place at a future date. In an effort to provide NDEI.org members with important information in selected areas, we have slide in our Slide Library that will contain material Not Published in Manuscript form as of this date. All such slides will be so indicated with the symbol:   in the upper right hand corner.
