Is there a template available that allows easy publishing of poem book?
I would highly recommend the memoir
document class for latex. It has it's own version of the verse
environment, plus a lot more nice things. Check the section in the memoir manual, it's a thing of beauty all on it's own.
Anyway, the relevant bits I gleaned from Memoir are below. The re-defining of the macro \PoemTitle makes the otherwise centered poem title flush with the left edge of the poem body.
\documentclass[a5paper,10pt,twoside]{memoir}
\renewcommand{\PoemTitlefont}{%
\normalfont\scshape\flushleft% Remove centering from poem title
\hspace*{0.5\linewidth}\hspace*{-0.5\versewidth}}% Makes poem title flush left with body block.
\checkandfixthelayout
\begin{document}
\settowidth{\versewidth}{my looooongest poem line}
\PlainPoemTitle % Removes the counter from \PoemTitle
\PoemTitle{My Poem Title}
\begin{verse}[\versewidth]
This is my poem,\\
isn't it nice?\\
This is my poem,\\
please read it twice\\
and one,\\
loooooooooooong poem line\\
right at the end!\\
\end{verse}
\end{document}
See the LaTeX package verse
