@code{\score} block.
+Remember that even in a file containing only a @code{\score} block, it
+is implicitly enclosed in a \book block. A \book block in a source
+file produces at least one output file, and by default the name of the
+output file produced is derived from the name of the input file, so
+@file{fandangoforelephants.ly} will produce
+@file{fandangoforelephants.pdf}.

+@subsection Multiple output files from one input file
+
+If you want multiple output files from the same @file{.ly} file,
+then you can add multiple @code{\book} blocks, where each
+such \book block will result in a separate output file.
+If you do not specify any @code{\book} block in the
+input file, LilyPond will implicitly treat the whole
+file as a single \book block, see
+@ref{File structure}.
+
+When producing multiple files from a single source file, Lilypond
+ensures that none of the output files from any @code{\book} block
+overwrites the output file produced by a preceding @code{\book} from
+the same input file.
+
+It does this by adding a suffix to the output name for each
+@code{\book} which uses the default output file name derived from the
+input source file.
+
+The default behaviour is to append a version-number suffix for each
+name which may clash, so
+
+@example
+\book @{
+ \score @{ @dots{} @}
+ \layout @{ @dots{} @}
+@}
+\book @{
+ \score @{ @dots{} @}
+ \layout @{ @dots{} @}
+@}
+\book @{
+ \score @{ @dots{} @}
+ \layout @{ @dots{} @}
+@}
+@end example
+
+in source file @file{eightminiatures.ly}
+will produce
+
+@itemize
+@item
+@file{eightminiatures.pdf},

+@subsection Output file names

+
+Lilypond provides facilities to allow you to control what file names
+are used by the various back-ends when producing output files.
+
+In the previous section, we saw how Lilypond prevents name-clashes when
+producing several ouputs from a single source file. You also have the
+ability to specify your own suffixes for each @code{\book} block, so
+for example you can produce files called
+@file{eightminiatures-Romanze.pdf}, @file{eightminiatures-Menuetto.pdf}
+and @file{eightminiatures-Nocturne.pdf} by adding a
+@code{\bookOutputSuffix} declaration inside each @code{\book} block.
+
+@example
+\book @{
+ \bookOutputSuffix "Romanze"
+ \score @{ @dots{} @}
+ \layout @{ @dots{} @}
+@}
+\book @{
+ \bookOutputSuffix "Menuetto"
+ \score @{ @dots{} @}
+ \layout @{ @dots{} @}
+@}
+\book @{
+ \bookOutputSuffix "Nocturne"
+ \score @{ @dots{} @}
+ \layout @{ @dots{} @}
+@}
+@end example
+
+You can also specify a different output filename for @code{book} block,
+by using @code{\bookOutputName} declarations
+
+@example
+\book @{
+ \bookOutputName "Romanze"
+ \score @{ @dots{} @}
+ \layout @{ @dots{} @}
+@}
+\book @{
+ \bookOutputName "Menuetto"
+ \score @{ @dots{} @}
+ \layout @{ @dots{} @}
+@}
+\book @{
+ \bookOutputName "Nocturne"
+ \score @{ @dots{} @}
+ \layout @{ @dots{} @}
+@}
+@end example
+
+The file above will produce these output files:
+
+@itemize
+@item
+@file{Romanze.pdf},
+@item
+@file{Menuetto.pdf} and
+@item
+@file{Nocturne.pdf}.
