All data entering the CSD are subject to stringent check and evaluation procedures. Some of these are visual, but the majority are automated within the CSD program PreQuest. The checks ensure that the 1D and 2D information fields abstracted by CCDC staff are accurately encoded, and that the 3D crystallographic coordinates are consistent with both the chemical description of the structure and with the geometrical description supplied by the authors. Most typographical errors in original papers can be corrected by the CCDC but, in the case of serious discrepancies, the original authors are consulted.
