同时使用 multibbl 和 natbib？

Question 1

简短的回答是，不会，这些包不会自然共存multibbl和natbib对不兼容的内部引用命令进行各种重新定义。

明智的答案是，对于多个书目，使用biblatex可能会容易得多，因为它可以轻松处理多个书目（例如这个答案) 和 (使用natbib包选项) 将定义所有命令，如\citeauthor等，因此具有两者的功能 multibbl和natbib在一个封装中。

较长的回答是，似乎确实有可能让这两个包的元素一起工作，但这并不优雅，不幸的是，longnamesfirst到目前为止我还没有找到一种方法来工作。主要的不兼容性在于它们对的重新定义\@citex，multibbl将其重新定义为

\def\@citex[#1]#2#3{%
  \let\@citea\@empty
  \@cite{\@for\@citeb:=#3\do
    {\@citea\def\@citea{,\penalty\@m\ }%
     \edef\@citeb{\expandafter\@firstofone\@citeb\@empty}%
     \@ifundefined{#2@auxfile}{}{\expandafter\immediate%
        \write\csname #2@auxfile\endcsname{\string\citation{\@citeb}}}%
     \@ifundefined{b@\@citeb}{\mbox{\reset@font\bfseries ?}%
       \G@refundefinedtrue
       \@latex@warning
         {Citation `\@citeb' on page \thepage \space undefined}}%
       {\hbox{\csname b@\@citeb\endcsname}}}}{#1}}

插入一个额外的参数并交换默认值

\if@filesw\immediate\write\@auxout{\string\citation{\@citeb}}\fi

为了

\@ifundefined{#2@auxfile}{}{\expandafter\immediate%
\write\csname #2@auxfile\endcsname{\string\citation{\@citeb}}}%

尽管natbib是否\let\@citex\NAT@citex或\let\@citex\NAT@citexnum取决于包选项。因此，我们需要在这两个命令中插入额外的文件.aux名参数\citeyear。\citeauthornatbib不依赖\@citex而是有自己的调用，它也必须调整为接受两个参数，第一个是.aux文件名，第二个是引用键。

打包成一个文件，一些必要的更改似乎

\begin{filecontents}{bibexample.bib}
@book{goossens93,
    author    = "Michel Goossens and Frank Mittelbach and Alexander Samarin",
    title     = "The LaTeX Companion",
    year      = "1993",
    publisher = "Addison-Wesley",
    address   = "Reading, Massachusetts"
}
