hello;

I noticed that the default \parskip is zero on my
system. This is because when I have this file:

------- start file -----

\documentclass[onecolumn]{article}
\begin{document}

line 1


line 2

\end{document}

------ end file -----

Now I Latex the above file and look at the output
and I see this:

line 1
line 2

i.e. no spacing between paragraphs.

I am using this:

This is TeXk, Version 3.14159 (Web2C 7.4.5)

on cygwin.

(if I use \par same result).

But when I added this line

\setlength{\parskip}{3pt plus 2pt}

then I can now see the spacing between paragraphs.

Is this the normal behavior? it seems odd to me that
I have to tell latex to add vertical spacing between
paragraphs, when the whole point of a paragraph is
that.

thank you,
--nospam

default value

\documentclass{article}
\begin{document}
\the\parskip
\end{document}

no it isn't, there should not be any spacing between paragraphs
and that is the default. It has a little bit of glue but that all.

Actually, the default value is 0pt plus 1pt. How do I know that. Because
I saw the file latex.ltx and it contains the line

\parskip=0pt plus 1pt

Why do you say that? Open any ordinary book. Do you see any vertical
space between paragraphs? I don't.

Best regards,

quite a few american textbooks (in math or economics) actually use the
noindentation + vertical space between paragraphs, which is why I have a lot of
problems convincing our students not to use this layout.

Yes, this is what I was expecting. I did the \noindent, but
was expecting a vetrical space.

But it is more readable when there is a vertical space
between paragraphs.

Clearly if your students prefer vertical space bettwen pars and
with no indenting (which is what I also prefer, and I am a
student too :), may be it is becuase it is easier to read
that way?

\noindent is only to suppress indentation of a single paragraph. To
change/suppress indentation globally adjust \parindent. Or, better
yet, use the setspace-package.

I disagree. I think it is terrible in longer texts and it reduces
readability. Which is why most books (all that I own) use only
indentation but no vertical space.

No. It's because they use(d) Word and there they marked paragraphs
with one blank line. They never thought about it, hardly anyone does.
But it looks terrible (imho -- but I'm not alone).

I agree with you guys now. I now have removed the \noindent and
removed the vertical spacing between pars as well.

May be working with word for so long got me into this
habit, but after looking at many books I have, I agree
that this way looks more professional. I am trying
to get away from using word alltogother if I can.

Most typographic manuals advise people not to use the noindentation + blank
space between paragraphs.

Word may be good for some things, but typographic considerations have never been
an issue with word.

In the case that you change it again :-) read the FAQ:

Thanks for warning for this pitfall. I removed the \setlength{\parskip}{1.0mm}(I didn't use the noindent,
I was only missing the mark 50%), and indeed, instantly it looks much more professional. Wow, and that just
before the manual goes to print.
