PEER Reports: LaTex Template

January 15, 2019

PEER has just released a LaTex report template for use in creating PEER-formatted research reports. This template was developed in response to requests from researchers to include a LaTex template in addition to the current WORD template. This LaTex template approximates as closely as possible the current WORD template.

PEER would like to thank Professor Pedro Arduino and his research colleagues at the University of Washington for their generosity in letting PEER use their file as the basis for the PEER Report LaTex Template. PEER has included the CLS file, naturally, and has also...
