\subsection{Common Ground and Recaps in Mathematical Textbooks}
The situation in mathematical textbooks is similar in structure to that in research papers
--perhaps more pronounced. Consider the following passage from Rudin's classical
introductory textbook to Functional Analysis~\cite[p. 6f]{Rudin:fa73}.
\begin{labeledquote}\sf
\textbf{1.5 Topological spaces} A \emph{topological space} is a set $S$ in which a
collection $\tau$ of subsets (called \emph{open sets}) has been specified, with the
following properties: $S$ is open, $\emptyset$ is open, [\ldots] Such a collection is
called a \emph{topology} on $S$. [\ldots]
\end{labeledquote}
and later -- vector spaces have been recapped earlier in section 1.4:
\begin{labeledquote}\sf
\textbf{1.6 Topological vector spaces} Suppose $\tau$ is a topology on a vector space $X$
such that
\begin{compactenum}[(a)]
\item \emph{every point of $X$ is a closed set, and}
\item \emph{the vector space operations are continuous with respect to $\tau$}
\end{compactenum}
Under these conditions, $\tau$ is said to be a \emph{vector topology} on $X$, and $X$ is a
\emph{topological vector space}.
\end{labeledquote}
Note that Rudin does not directly cite the literature in these quotes, but in the preface
he mentions the vast literature on function analysis and in Appendix B he cites the
original literature for each chapter. The situation in textbooks is also different from
research articles in that textbooks -- like survey articles, and by their very nature --
do not add new knowledge or new results, but aggregate and organize the already published
ones, possibly reformulating them for a more uniform exposition. But still, one can
