我正在尝试制作带有参考书目的简单乳胶文档，由 Zotero 生成（以 导出biblatex，编码为“ISO Western 8859-1”）。对于参考书目，我使用biblatexwithbiber作为后端并尝试实现biblatex-chicago authordate样式。
以下是代码：

输出如下：
我遇到的主要问题是字段过多。例如，在上面的输出中，我有“访问日期”[来自urldate.bib 文件中的文件]，我无法消除它，比如说，以消除出版语言的方式。 自定义 biblatex 样式的指南可以达到这个目的：
\AtEveryBibitem{\clearname{urldate}}
\AtEveryBibitem{\clearlist{urldate}}
\AtEveryBibitem{\clearfield{urldate}}
此外，我需要这个字段来存储在线资料，所以我需要一个不同的解决方案。我在其他字段上也遇到了类似的问题，我只需要从 .bib 数据库中删除它们。例如，PNAS 的文章有 PMID 编号，即使有，它也打印在参考书目中
eprint=false
在序言中。
biblatex我做错了什么？我知道这里的专家可以编写复杂的代码来解决这个特定问题，但也许有人知道如何使用或提供的选项来解决它biblatex-chicago？
答案1
你可能\AtEveryBibitem{\clearfield{urldate}}想尝试一下
\AtEveryBibitem{%
\ifentrytype{online}
{}
{\clearfield{urlyear}\clearfield{urlmonth}\clearfield{urlday}}}
这确保仅对非条目urldate删除 （实际上，是其部分urlyear、urlmonth和） 。urlday@online
一般来说，人们需要对外部程序导出的文件稍加小心，.bib因为这些文件有时不符合最佳实践。
不过，您的资料来源看起来相当不错，除了issn = {0027-8424, 1091-6490},in enikolopov_field_2013、isbn = {9781107306882 1107306884 9781107314634 1107314631 9781139343824 1139343823},insimpser_why_2013和几个language = {en},。 ISSN 和 ISBN 字段不应同时包含多个 ISSN/ISBN，因为这些字段打印得很冗长，而且您肯定不想在参考书目中看到所有 6 个不同的 ISBN，请使用您使用的书籍副本背面的 ISBN。而在字段中，language“[l]语言可以按字面或本地化键指定”（biblatex文档，§2.2.2数据字段，第 19 页），本地化密钥版本更适合本地化目的，因此english比 更好en。
