+
+\maketitle
+
+ \begin{abstract}
+ This guide is for authors who are preparing papers for the
+ journals of the London Mathematical Society using the
+ \LaTeX\ document-preparation system and the LMS style file.
+ \end{abstract}
+
+\tableofcontents
+
+\section{Introduction}
+
+In addition to the standard submission of hardcopy from authors, the
+journals of the London Mathematical Society (LMS) now accept machine-readable
+forms of papers in \LaTeX. Initially, only the {\em Bulletin\/} will be
+accepting \LaTeX\ articles, but this is expected to be extended to the {\em
+Journal\/} and {\em Proceedings\/} in due course. The layout design for the
+LMS has been implemented as a \LaTeX\ style file, based on the \verb"article"
+style as discussed in the \LaTeX\ manual \cite{LaTeX}.
+Commands which differ from the standard \LaTeX\ interface, or which are
+provided in addition to the standard interface, are explained in this
+guide (which is {\em not} a substitute for the \LaTeX\ manual itself).
+Authors planning to submit their papers in \LaTeX\ are advised to use
+\verb"lms.sty" as early as possible in the creation of their files. (Note
+that files using Plain \TeX, AMS\TeX\ or other variants cannot be used. Also,
+the style is suitable only for papers, {\em not\/} for obituaries or book
+reviews, although these may be available later.)
+
+\subsection{Introduction to \LaTeX}
+
+\LaTeX\ is constructed as a series of macros on top of the \TeX\
+typesetting program.
+\LaTeX\ adds to \TeX\ a collection of facilities which simplify typesetting
+for authors by allowing them to concentrate on the logical structure of the
+document rather than its visual layout.
+Careful use of the \LaTeX\ mark-up philosophy results in uniform
+layout rather than the {\em ad hoc\/} results of some word-processing systems.
+Authors are advised to let the defaults control font selection etc.,
+rather than tinker themselves.
+
+\LaTeX\ provides a consistent and comprehensive document-preparation
+interface. Amongst other things, \LaTeX\ can automatically number list
+entries, equations, figures, tables and footnotes, as well as sections and
+subsections. Using this numbering system, bibliographic citations, page
+references and cross references to any other numbered entity (e.g. sections,
+equations, figures) are straightforward.
+
+\subsection{The LMS document style}
+
+The use of document styles allows a simple change of style (or style
+option) to transform the appearance of your document.
+The LMS style file preserves the
+standard \LaTeX\ interface such that any document which can be produced
+using the standard \LaTeX\ \verb"article" style can also be produced with
+the LMS style.
+However, the measure (or width of text) is 15pt (5mm) wider than the default
+for 10pt \verb"article", therefore line breaks will change. Authors are urged
+to use \verb"lms.sty" from the beginning of their document preparation; in
+particular, they are advised not to use wider measures as given by
+\verb"a4.sty" etc., because this will involve truncating long lines at a later stage.
+
+\subsection{General style issues}
+
+Use of \LaTeX\ defaults will result in a pleasing uniformity of layout
+and font selection. Authors should resist the temptation to make
+{\em ad hoc\/} changes to these. Also avoid use of direct formatting unless
+really necessary. Papers will be edited as usual, and this process may be
+obstructed by the use of inserted line breaks, etc.
+
+In addition to the standard \LaTeX\ fonts, authors can use the
+AMS {\em msam\/} and {\em msbm\/} fonts (see Subsection~\ref{sec:fonts}
+below). The final makeup will use Times Roman fonts, and if these are
+available to authors (e.g. via PS\LaTeX) they should be employed in order
+to ensure good use of space (they are in general more economical than
+computer modern fonts).
+
+For general style issues, authors are referred to the `Preparation of
+manuscripts' in the {\em Bulletin} of the LMS. Authors who are interested in
+the details of style are referred to \cite{Butcher} and \cite{Chicago}. The
+language used in the journals is British English, and spelling should conform
+to this.
+
+Use should be made of symbolic references (\verb"\ref") in order to
+protect against late changes of order, etc.
+
+\subsection{Submission of \LaTeX\ articles to the LMS}
+
+Authors who intend to submit a \LaTeX\ article to the LMS should obtain a
+copy of the style file \verb"lms.sty". This is available by anonymous FTP from
+\begin{verbatim}
+
+ ftp.cup.cam.ac.uk
+
+\end{verbatim}
+You will find the style file, instructions and sample pages concatenated into a single file \verb"lms.all" in the directory
+\begin{verbatim}
+
+ /pub/texarchive/journals/latex
+
+\end{verbatim}
+If you cannot obtain the LMS style file, use \verb"article" style.
+
+When submitting the final article, ensure that the following are included and clearly labelled.
+\begin{enumerate}
+ \item Hardcopy printout of the article
+ \item The input file (exactly matching hardcopy)
+ \item A copy of all user-defined macros
+ \item Bibliography files, or if you have used B{\sc ib}\TeX, the \verb".bib"
+ and \verb".bbl" files
+ \item Any other files necessary to prepare the article
+ for typesetting
+\end{enumerate}
+The files for the {\em final\/} article should be text-only with no
+system-dependent control codes, on a PC disk. If you are working on a
+Macintosh, please use Apple File Exchange with the following options to
+convert your file(s) to PC format.
+\begin{enumerate}
+\item Replace CR with CR/LF
+\item Special characters: change to closest single character
+\item Tab characters: Neither
+\end{enumerate}
+Submit the above by post to the appropriate member of the Editorial Board as
+described on the inside back cover of each issue of the {\em Bulletin}.
+
+\section{Using the LMS style}
+
+First, copy the file \verb"lms.sty" into an appropriate subdirectory on
+your system.
+The LMS style is implemented as a complete document style, {\em
+not\/} an option.
+In order to use the LMS style, replace \verb"article" by \verb"lms" in the
+\verb"\documentstyle" command at the beginning of your document: that is,
+%
+\begin{verbatim}
+
+ \documentstyle{article}
+
+\end{verbatim}
+%
+is replaced by
+%
+\begin{verbatim}
+
+ \documentstyle{lms}
+
+\end{verbatim}
+%
+In general, the following standard document style options should {\em
+not\/} be used with the LMS style:
+%
+\begin{itemize}
+ \item {\tt 10pt}, {\tt 11pt}, {\tt 12pt} -- unavailable;
+ \item {\tt draft}, {\tt twoside} -- {\tt twoside} is the default;
+ \item {\tt fleqn}, {\tt leqno}, {\tt titlepage}, {\tt twocolumn} --
+ should not be used (\verb"fleqn" is already incorporated into
+ the LMS style).
+\end{itemize}
+%
+However, {\tt proc}, {\tt ifthen}, {\tt bezier} can be used if
+necessary.
+
+At the beginning of the source code for this guide, you will find the
+following code.
+%
+\begin{verbatim}
+
+ %%% oldfss = LaTeX without NFSS
+ %%% nfssone = LaTeX with New Font Selection Scheme v1
+ %%% nfsstwo = LaTeX with New Font Selection Scheme v2
+
+ %%% noams = No AMS fonts, sample pages will substitute some
+ characters
+ %%% amsone = AMS v1 fonts
+ %%% amstwo = AMS v2 fonts (the recommended option)
+
+ %%% Uncomment ONE of the following combinations:
+
+ \onetrue % oldfss/noams
+ % \twotrue % oldfss/amsone (mssymb.tex)
+ % \threetrue % oldfss/amstwo (amssym.def,amssym.tex)
+ % \fourtrue % nfssone/noams
+ % \fivetrue % nfssone/amstwo (amsfonts.sty,amssymb.sty)
+ % \sixtrue % nfsstwo/noams
+ % \seventrue % nfsstwo/amstwo (amsfonts.sty,amssymb.sty)
+
+\end{verbatim}
+
+Before you process your document, you should uncomment one of these options,
+according to your system. The default is \verb"\onetrue". There is
+more about the effects of these options in Subsection~\ref{sec:fonts}.
+
+\section{Additional facilities}
+
+In addition to all the standard \LaTeX\ design elements, the LMS style
+includes the following features.
+%
+\begin{enumerate}
+ \item Commands for typesetting the title page
+ \item Ability to create new environments for examples,
+ exercises, problems, definitions,
+ notations, notes, remarks, conjectures,
+ corollaries, lemmas, propositions, theorems,
+ etc.
+ \item Proof environment
+ \item Noteinproof environment
+ \item Acknowledgements environment
+ \item Environments to produce affiliation addresses
+ \item Control of enumerated lists
+ \item Fonts---NFSS, AMS
+\end{enumerate}
+%
+In general, once you have used the additional \verb"lms.sty"
+facilities in your document, do not process it with a standard \LaTeX\
+style file.
+
+\subsection{Typesetting the title page}
+
+At the beginning of your article, the title should be generated in the
+usual way using the \verb"\maketitle" command. Immediately following the
+title you may include an abstract. For example, the titles for this guide were produced by the following source.
+%
+\begin{verbatim}
+
+ \extraline{An extra footnoteline is available for funding
+ information if required.}
+ \classno{28C15}
+
+ \begin{document}
+
+ \title[\LaTeX\ style file for London Mathematical Society
+ journals]{\LaTeX\ style file for submission to\\
+ the London Mathematical Society journals}
+ \author{Rod Mulvey \and\ Alison Woollatt}
+
+ \maketitle
+
+ \begin{abstract}
+ This guide is for authors who are preparing papers for the
+ journals of the London Mathematical Society using the
+ \LaTeX\ document-preparation system and the LMS style file.
+ \end{abstract}
+
+\end{verbatim}
+
+Note that there is a new command -- \verb"\extraline" -- which gives an
+extra footnote on the title page, and which is typically used for funding
+information. The 1991 {\it Mathematics Subject Classification\/} number
+will be inserted as a footnote. To insert the number, you use another
+new command -- \verb"\classno". The classificaton number on the title
+page of this guide was typeset using: \verb"\classno{28C15}".
+
+In the LMS style, the title of the article and the author's name (or
+authors' names) are used both at the beginning of the article for the main
+title and throughout the article as running headlines at the top of every
+page.
+The title is used on odd-numbered pages (rectos) and the author's name
+appears on even-numbered pages (versos).
+Although the main heading can run to several lines of text, the running
+headline must be a single line.
+Moreover, the main heading can incorporate new-line commands
+(e.g. \verb"\\"), but these are not acceptable in a running headline.
+To enable you to specify an alternative short title, which should be not
+more than 48 characters and spaces, and an alternative short author's name,
+the standard \verb"\title" and \verb"\author" commands have been extended
+to take an optional argument to be used as the running headline.
+
+\subsection{Creating new environments}
+
+You can create your own environments in \LaTeX, and although you may already
+be familiar with \verb"\newtheorem", you will not have seen the other two commands explained below.
+\begin{enumerate}
+ \item \verb"\newtheorem" is used for creating new theorem-like
+ environments, such as theorems, corollaries, lemmas,
+ conjectures and propositions, with the body of the text
+ (automatically) in italic.
+ \item \verb"\newnumbered" is used for creating new numbered environments,
+ such as\break examples, exercises and problems, with the body of
+ the text in roman.
+ \item \verb"\newunnumbered" is used for creating new
+ {\it un\/}numbered environments, such as remarks, notes
+ and definitions, also with the body of the text in roman.
+\end{enumerate}
+
+\subsubsection{\tt \char"5C newtheorem}
+
+You can set up numbered and unnumbered theorem-like environments to
+produce, for example, the following output.
+ \newtheorem{corollary}{Corollary}
+ \begin{corollary}[An optional argument]
+ Let $G$ be the free group on the generators $\langle
+ y_n\rangle^\infty_{n=1}$. There is a finite partition of
+ $G\times G$ such that one cannot find $(a,b)\in G\times G$ and
+ $d\in FP(\langle y_n\rangle ^\infty_{n=1})$ with either
+ $(a,b)\approx (ad,b)\approx (a,bd)$ or $(a,b)\approx (da,b)
+ \approx (a,db)$.
+ \end{corollary}
+ \begin{corollary*}
+ An unnumbered corollary will start like this.
+ \end{corollary*}
+\noindent To do this, create the corollary environment in the preamble
+%
+\begin{verbatim}
+
+ \newtheorem{corollary}{Corollary}
+
+\end{verbatim}
+%
+and use it as follows in the document.
+%
+\begin{verbatim}
+
+ \begin{corollary}[An optional argument]
+ Let $G$ be the free group on the generators $\langle
+ y_n\rangle^\infty_{n=1}$. There is a finite partition of
+ $G\times G$ such that one cannot find $(a,b)\in G\times G$ and
+ $d\in FP(\langle y_n\rangle ^\infty_{n=1})$ with either
+ $(a,b)\approx (ad,b)\approx (a,bd)$ or $(a,b)\approx (da,b)
+ \approx (a,db)$.
+ \end{corollary}
+ \begin{corollary*}
+ An unnumbered corollary will start like this.
+ \end{corollary*}
+
+\end{verbatim}
+
+The \verb"\newtheorem" command has the usual optional arguments (see
+\cite[p.~174]{LaTeX}), which can be used to control the numbering of
+these environments.
+
+\subsubsection{{\tt \char"5C newnumbered}\enskip and\/ {\tt \char"5C newunnumbered}}
+
+Theorem-like environments have the\break body of the theorem in italics. This
+is inappropriate for environments like example, exercise and remark, which
+require the text to be roman. These may be created by the commands
+\verb"\newnumbered" (which gives you a numbered environment) and
+\verb"\newunnumbered" (which gives you an unnumbered environment); both are
+used just like \verb"\newtheorem". You can control the numbering of
+\verb"\newnumbered" environments in exactly the same way as you do for
+theorems, by using optional arguments, as mentioned above.
+ \newnumbered{example}{Example}
+ \newunnumbered{notation}{Notation}
+ \begin{example}
+ Let $H$ be a real infinite dimensional Hilbert space with
+ orthonormal basis $\{e_n\}$. We define a linear isometry
+ $A:H\rightarrow H$ by \ldots\ but $u_n \not\rightarrow u$.
+ \end{example}
+ \begin{example*}
+ You can have an example unnumbered if you use an asterisk in
+ the source code. This gives the same layout as an unnumbered
+ environment (see below).
+ \end{example*}
+ \begin{notation}
+ This is mostly standard.
+ \end{notation}
+\noindent The above is produced by typing in the preamble
+\begin{verbatim}
+
+ \newnumbered{example}{Example}
+ \newunnumbered{notation}{Notation}
+
+\end{verbatim}
+and in the document the following.
+\begin{verbatim}
+
+ \begin{example}
+ Let $H$ be a real infinite dimensional Hilbert space with
+ orthonormal basis $\{e_n\}$. We define a linear isometry
+ $A:H\rightarrow H$ by \ldots\ but $u_n \not\rightarrow u$.
+ \end{example}
+ \begin{example*}
+ You can have an example unnumbered if you use an asterisk in
+ the source code. This gives the same layout as an unnumbered
+ environment (see below).
+ \end{example*}
+ \begin{notation}
+ This is mostly standard.
+ \end{notation}
+
+\end{verbatim}
+
+Note from this example that you can suppress the numbering on a \verb"\newnumbered" environment, and that the result is the same
+as if you had defined a \verb"\newunnumbered" environment.
+
+\subsection{{\tt proof} environment}
+
+An environment exists for proofs, and it can take an optional argument.
+ \begin{proof}[of Theorem~{\rm 27}]
+ We define a linear isometry $A:H\rightarrow H$ by the nonlinear
+ Schr\"{o}dinger equation. It would not be hard to modify the
+ proof to obtain an analogous result for ellipsoids rather than
+ spheres.
+ \end{proof}
+\noindent This is produced by typing the following.
+\begin{verbatim}
+
+ \begin{proof}[of Theorem~{\rm 27}]
+ We define a linear isometry $A:H\rightarrow H$ by the nonlinear
+ Schr\"{o}dinger equation. It would not be hard to modify the
+ proof to obtain an analogous result for ellipsoids rather than
+ spheres.
+ \end{proof}
+\end{verbatim}
+
+
+\subsection{{\tt noteinproof} environment}
+
+The \verb"noteinproof" environment has been set up for material added at
+the proof stage.
+
+ \begin{noteinproof}
+ We define a linear isometry $A:H\rightarrow H$ by the nonlinear
+ Schr\"{o}dinger equation. It would not be hard to modify the
+ proof to obtain an analogous result for ellipsoids rather than
+ spheres.
+ \end{noteinproof}
+\noindent The above was generated by typing the following.

+
+\end{verbatim}
+
+\subsection{Affiliation addresses}
+
+Affiliation(s) appear at the end of an article. The LMS style allows up to
+four affiliations, using \verb"\affiliationone", \verb"\affiliationtwo",
+\verb"\affiliationthree" and \verb"\affiliationfour". The addresses at the
+end of this guide were produced using the following.
+\begin{verbatim}
+
+ \affiliationone{Cambridge University Press\\
+ Printing Division\\ Shaftesbury Road\\ Cambridge CB2 2BS}
+ %
+ \affiliationtwo{School of Mathematical Sciences\\
+ Queen Mary and Westfield College\\ Mile End Road\\ London E1 4NS}
+
+\end{verbatim}
+
+\subsection{Lists}
+
+The LMS style provides three standard list environments:
+\begin{itemize}
+ \item numbered lists, created using the \verb"enumerate" environment;
+ \item bulleted lists, created using the \verb"itemize" environment;
+ \item labelled lists, created using the \verb"description" environment.
+\end{itemize}
+The enumerated list numbers each list item with a small roman numeral in parentheses.
+Alternative styles can be achieved by inserting a redefinition of the
+number labelling command after \verb"\begin{enumerate}".
+For example, a list numbered with arabic numerals inside parentheses can be
+produced by the following.
+%
+\begin{verbatim}
+
+ \begin{enumerate}
+ \renewcommand{\theenumi}{(\arabic{enumi})}
+ \item First item
+\end{verbatim}
+~~~~~~~~~~~~~~~\vdots
+\begin{verbatim}
+ \end{enumerate}
+
+\end{verbatim}
+%
+This produces the following list.
+%
+\begin{enumerate}
+ \renewcommand{\theenumi}{(\arabic{enumi})}
+ \item First item
+ \item second item
+ \item etc.
+\end{enumerate}
+
+\subsection{Fonts}
+\label{sec:fonts}
+
+There are at present two `font selection schemes' in use for \LaTeX;
+these govern the use and interpretation of commands like \verb"\bf",
+\verb"\rm". The {\it old font selection scheme\/} is at present the
+\LaTeX\ default, and is described in \cite{LaTeX}. The {\it new font
+selection scheme} has been introduced in later versions of \LaTeX\ and, of course, in \LaTeX 2$\epsilon$. The LMS style will
+operate without modification using either font selection scheme.
+
+There are also two series of fonts designed by the American Mathematical
+Society ({\em msam} and {\em msbm}), and these can be used if desired.
+The AMS fonts contain slanted versions of the greater than or equal
+to, and less than or equal to, signs; these slanted versions are
+preferred by the LMS and so are substituted whenever \LaTeX\ commands like \verb"\ge" are used.
+Authors without the AMS fonts can thus use the standard \LaTeX\ forms,
+\verb"\ge" or \verb"\geq" and \verb"\le" or \verb"\leq".
+
+Table~\ref{fonts} shows all the combinations of versions of \LaTeX\ and AMS.
+You can see from the option you have chosen exactly which fonts are going
+to work for you, and which fonts you can expect to be substituted.
+
+(If you need to specify an extra font for use on your system, please do so
+with a generic command name defined in your preamble. We can then substitute
+the correct font globally.)
+%

+\caption[]{Font substitutions. A \tick\ means you will get the font you
+specified; otherwise, the font will be substituted with the one shown.}

+\section{Some guidelines for using standard facilities}
+
+The following notes may help you achieve the best effects with the LMS
+style file.
+
+\subsection{Sections}
+
+\LaTeX\ provides five levels of section headings, only three of which are
+defined in the LMS style file:
+%
+\begin{itemize}
+ \item \verb"\section"
+ \item \verb"\subsection"
+ \item \verb"\subsubsection"
+\end{itemize}
+
+\subsection{Running headlines}
+
+As described above, the title of the article and the author's name (or
+authors' names) are used as running headlines at the top of every page.
+The \verb"\pagestyle" and \verb"\thispagestyle" commands should {\em not\/}
+be used. Similarly, the commands \verb"\markright" and \verb"\markboth"
+should not be necessary.
+
+\subsection{Illustrations (or figures)}
+
+The LMS style will cope with most positioning of your illustrations, and you
+should not normally use the optional positioning qualifiers on the
+\verb"figure" environment which would override these decisions. A
+figure caption should be below the figure itself, therefore the
+\verb"\caption"
+command should appear after the figure or space left for an illustration.
+For example, Figure~\ref{sample-figure} is produced using the following.
+%
+\begin{verbatim}
+
+ \begin{figure}
+ \centering
+ \vspace{5cm}
+ \caption{An example figure in which space has been
+ left for the artwork}
+ \label{sample-figure}
+ \end{figure}
+
+\end{verbatim}
+%
+ \begin{figure}
+ \centering
+ \vspace{5cm}
+ \caption{An example figure in which space has been
+ left for the artwork}
+ \label{sample-figure}
+ \end{figure}
+
+\subsection{Tables}
+
+The LMS style will cope with most positioning of your tables,
+and you should not normally use the optional positioning qualifiers on the
+\verb"table" environment which would override these decisions.
+Table captions should be at the top, therefore the \verb"\caption" command
+should appear before the body of the table.
+
+The \verb"tabular" environment should be used to produce ruled tables;
+it has been modified for the LMS style in the following ways.
+%
+\begin{enumerate}
+ \item Additional vertical space is inserted on either side of a rule.
+ \item Vertical lines are not produced.
+\end{enumerate}
+%
+Commands to redefine quantities such as \verb"\arraystretch" should be
+omitted.
+For example, Table~\ref{symbols} is produced using the following.
+%
+\begin{verbatim}
+
+ \begin{table}
+ \caption{Components of generating functions}
+ \begin{tabular}{ccc}
+ \hline
+ $k$ & $\alpha_k(x)$ & $l_k(x)$\\
+ \hline
+ 1 & 1 & 1 \\
+ 2 & $x^3$ & $x^3$\\
+ 3 & $2x^5$ & $2x^5$\\
+ 4 & $2x^7$ & $x^6+2x^7$\\
+ 5 & $2x^7+2x^9$ & $2x^7+2x^9$\\
+ 6 & $2x^{11}$ & $4x^8+2x^{11}$\\
+ 7 & $4x^9+2x^{13}$ & $4x^9+2x^{13}$\\
+ 8 & $2x^9+2x^{15}$ & $3x^9+4x^{10}+2x^{15}$\\
+ 9 & $4x^{11}+2x^{17}$ & $4x^{10}+4x^{11}+2x^{17}$\\
+ \hline
+ \end{tabular}
+ \label{symbols}
+ \end{table}
+
+\end{verbatim}
+ \begin{table}
+ \caption{Components of generating functions}
+ \begin{tabular}{ccc}
+ \hline
+ $k$ & $\alpha_k(x)$ & $l_k(x)$\\
+ \hline
+ 1 & 1 & 1 \\
+ 2 & $x^3$ & $x^3$\\
+ 3 & $2x^5$ & $2x^5$\\
+ 4 & $2x^7$ & $x^6+2x^7$\\
+ 5 & $2x^7+2x^9$ & $2x^7+2x^9$\\
+ 6 & $2x^{11}$ & $4x^8+2x^{11}$\\
+ 7 & $4x^9+2x^{13}$ & $4x^9+2x^{13}$\\
+ 8 & $2x^9+2x^{15}$ & $3x^9+4x^{10}+2x^{15}$\\
+ 9 & $4x^{11}+2x^{17}$ & $4x^{10}+4x^{11}+2x^{17}$\\
+ \hline
+ \end{tabular}
+ \label{symbols}
+ \end{table}
+
+\subsection{Displayed mathematics}
+
+The LMS style will centre displayed mathematics. You should use the \LaTeX\
+standard of open and closed square brackets as delimiters for unnumbered
+equations. The equation
+ \[ \sum_{i=1}^p \lambda_i = {\rmn {trace}}({\bld S}) \]
+was typeset in the LMS style with
+\begin{verbatim}
+
+ \[ \sum_{i=1}^p \lambda_i = {\rmn {trace}}({\bld S}) \]
+
+\end{verbatim}
+The same equation may be numbered by the use of
+\verb"\begin{equation}"\ldots\break\verb"\end{equation}".
+Note that \verb"\rmn" and \verb"\bld" will produce roman
+and bold face characters respectively in math mode. They have been
+defined in two ways in the source code of the guide: one for
+authors using the new font selection scheme, and the other for
+authors using the old font selection scheme.
+
+
+
+\subsection{Bibliography}
+
+References to published literature will automatically be inserted into the text; see examples below for style.
+References should be listed in a \verb"thebibliography" environment
+alphabetically by author name(s) and then by year if the same author
+has several papers. The author name(s) should be in the \verb"\bibname"
+environment, using \verb"\and" where necessary. To refer to one of the
+references, for instance \cite{Bargmann}, you just type
+\verb"\cite{Bargmann}" in your source file.
+
+The following listing shows some references prepared in the style of the
+{\em Bulletin}; it produces the references shown at the end of this guide.
