Biblatex - Shortauthor 长度问题

Question

我在工作中多次引用 Android 开源项目。因此，我多次声明同一个 shortauthor，如下所示：

@ONLINE{online_android_apiguides_services,
    TITLE        = {Android API Guides - Services},
    AUTHOR       = {{Android Open Source Project}},
    SHORTAUTHOR  = {AOSP},
    URL          = {http://developer.android.com/guide/components/services.html},
    URLDATE      = {2015-03-12}
 }
@ONLINE{online_android_reference_service,
    TITLE        = {Android Reference - Service},
    AUTHOR       = {{Android Open Source Project}},
    SHORTAUTHOR  = {AOSP},
    URL          = {http://developer.android.com/reference/android/app/Service.html},
    URLDATE      = {2015-03-12}
 }

期望输出为“[AOSPa]”和“[AOSPb]”。但实际输出为“[AOSa]”和“[AOSb]”。

一般来说，我想要 3 个字符的形式（就像当它自动对姓氏执行此操作时一样），但是当我明确声明一个简短的作者时，我不希望它被缩短。

提前致谢！

编辑

我这样声明参考书目：

\usepackage[backend=bibtex8,
        style=alphabetic]{biblatex}
\bibliography{mybib}

Answer 1

您可以使用该label字段。biblatex文档称，这label是“[a] 引用样式用来替代常规标签的指定，如果生成常规标签所需的任何数据缺失”（第 20 页biblatex文档）。幸运的是，由于alphabetic的样式label优先于labelname，因此它也可以完整使用。

因此

\documentclass{article}
\usepackage[backend=bibtex,
        style=alphabetic]{biblatex}

\usepackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@ONLINE{online_android_apiguides_services,
    TITLE        = {Android API Guides - Services},
    AUTHOR       = {{Android Open Source Project}},
    label  = {AOSP},
    URL          = {http://developer.android.com/guide/components/services.html},
    URLDATE      = {2015-03-12}
 }
@ONLINE{online_android_reference_service,
    TITLE        = {Android Reference - Service},
    AUTHOR       = {{Android Open Source Project}},
    label  = {AOSP},
    URL          = {http://developer.android.com/reference/android/app/Service.html},
    URLDATE      = {2015-03-12}
 }
\end{filecontents*}
\addbibresource{\jobname.bib}

\begin{document}
\nocite{*}
\printbibliography
\end{document}

完全符合您的要求。

如果您使用 Biber，则评论中所建议的方法shorthand同样有效；但是，使用 BibTeX(8) 则不会消除歧义。

\documentclass{article}
\usepackage[backend=biber,
        style=alphabetic]{biblatex}

\usepackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@ONLINE{online_android_apiguides_services,
    TITLE        = {Android API Guides - Services},
    AUTHOR       = {{Android Open Source Project}},
    shorthand  = {AOSP},
    URL          = {http://developer.android.com/guide/components/services.html},
    URLDATE      = {2015-03-12}
 }
@ONLINE{online_android_reference_service,
    TITLE        = {Android Reference - Service},
    AUTHOR       = {{Android Open Source Project}},
    shorthand  = {AOSP},
    URL          = {http://developer.android.com/reference/android/app/Service.html},
    URLDATE      = {2015-03-12}
 }
\end{filecontents*}
\addbibresource{\jobname.bib}

\begin{document}
\nocite{*}
\printbibliography
\end{document}
