indentationlists
I have an enumerate in which the items are paragraphs (sometimes more then 1 per item) and the paragraphs are indented after the label.
How can I change the behaviour so that from the second line of the item, it should start with normal margin (below the label)?
I am using book class.
Consider using the enumitem package to perform your list management. Here's an example of what you might be after:
\documentclass{article}
\usepackage{enumitem}% http://ctan.org/pkg/enumitem
\usepackage{showframe}% http://ctan.org/pkg/showframe
\begin{document}
\begin{description}
[align=left,style=nextline,leftmargin=*,labelsep=\parindent,font=\normalfont]
\item[FIRST ITEM] Note that my list definition is not indented
\item[SECOND ITEM] This one is also not indented and the description
is long enough to span two lines.
\end{description}
\end{document}
The optional argument to description performs:
align=left: Ensures a left-aligned item label;leftmargin=*: Left margin of description is flush with left margin of text block;style=nextline: Automates the process of using \hfill \\;labelsep=\parindent: The gap between the label and the start of the item is \labelsep, which is set to be the same as the regular paragraph indent.font=\normalfont: This modifies the default bold font of the description item to \normalfont.If need be, you can also create a new list environment to perform these "optional settings" automatically. For this, see \newlist and \setlist in the enumitem documentation (section 7 Cloning the basic lists, p 10).
showframe was only used to emphasize the text block boundaries within the example.
It's easy with the enumitem package:
\documentclass{article}
\usepackage[showframe]{geometry}
\usepackage{enumitem}
\usepackage{lipsum}
\begin{document}
\lipsum[1]
\begin{enumerate}[label=H\arabic*. , wide=0.5em, leftmargin=*]
\item \lipsum[2]
\item \lipsum[3]
\item \lipsum[4]
\end{enumerate}
\end{document}

You can change the
\itemindentlength to make it equal to\labelwidth+\labelsep, and perhaps also change the\leftamrgin. The enumitem package allows you to do those modifications easily. A little example:
