We are sorry, but COLM does not allow double submissions. All papers under the ARR process, regardless of stage, are considered as under submission to ARR, and cannot be submitted to COLM. COLM will conduct double submission checks following the full paper submission deadline. Only papers then under review will be checked. This means that papers withdrawn before, including abstracts with no full paper submitted, will not be considered or used for double submission checks. COLM cannot provide guarantees of compatiblity with regard to the policies and processes of other venues regarding double submissions, but this policy what we consider as under submission at COLM.
