「et Int」引用システムの使用

Question 1

残念ながら、論文では提案されたスタイルの実際の詳細があまり明確に説明されていなかったため、当面は私の解釈に従うしかありません。

この実装では、著者が 2 人以上の場合 (1 人の著者だけを「et int.」に置き換えるのは不公平なので、著者名をフルネームで表記したほうがよいでしょう)、著者番号の後bbx:etinttrunc、最後の著者の前にある「介在著者」を省略します。例では、bbx:etinttrunc質問にあるように 2 に設定されています。

Biber がこれをネイティブにサポートしていれば、物事はもっと簡単になると思いますが、このようにも動作します。

4 人の著者がいる作品で 3 人目の著者を省略する必要がある場合は、もう少し単純なが必要です\DeclareNameFormat{given-family-etint}。

    {\toggletrue{bbx:showetint}}
