ich bekomme mehrere Warnungen, wenn ich die Jahreszahlen z.B. eines mehrbändigen Werks oder Zeitschriften vermerke, deren Ausgabe über mehrere Jahre anzugeben ist. Es kommt stets eine solche Warnung: "Package biblatex Warning: Biber reported the following issues with 'leyerle:1993': - Entry 'leyerle:1993' (output.bib): Invalid format '1993-1995' of date field 'date' - ignoring." bzw. "BibTeX Entry 'leyerle:1993' (output.bib): Invalid format '1993-1995' of date field 'date' - ignoring"
Was kann man dagegen tun? Hier mein MWE
\documentclass{article}
