If available and not used for data import, additional report numbers are entered here. This includes identifiers from external systems such as from CERN, FZ Jülich, the arXiv preprint server and iNSPIRE.

Each report number is entered on a separate line. Please select the relevant source from the selection list. If several report numbers are entered in a single line separated by commas or semicolons, they are automatically distributed to individual lines. The associated source is determined automatically.
