# How to refer a section in another chapter?

To begin its not a LaTeX query but related to writing a report.

What is the best way to refer a Section in another Chapter in the report ?

I am using something like this,

As explained in Section 3 of Chapter 4 ?

On a related note, how do we refer a section in a journal or a book ?

Here, I am using something like this,

As stated in [2, 3.1.4]

Is this convention correct ?

Why don't you use packages like hyperref or cleveref. – Marco Daniel Oct 2 '11 at 11:37
I use hyperref package, however I was not clear on reference type that I need to put in the document – www.sapnaedu.in Oct 2 '11 at 11:42
But you can modify the output of the reference. It's much easier. ;-) – Marco Daniel Oct 2 '11 at 11:45
Ya, I would change the reference, since I am clear on type of reference I need to use. I use Lyx, and it gives a number of possibilities for cross-referencing, so I was confused. Thanks to you and Tex.SE :) – www.sapnaedu.in Oct 2 '11 at 12:01

For cross-referencing another section of the work at hand, I suggest

As explained in Section 4.3 ...

For citing a source, there are a lot of possible styles. However, the reader should always be able to tell apart source number and page/section numbers within the source. For the numeric style, I suggest

As stated in [2, p. 99] as well as in [2, section 3.1.4] ...

EDIT: Just in case it is not obvious: Cross-referencing should be done using commands like \label and \ref. The cleveref package is able to automatically detect the label type and write "section 4.3" instead of "4.3".

Thank you so much, I will have to rephrase every reference in my report now :) – www.sapnaedu.in Oct 2 '11 at 11:35
Your second example shows to possibilities, right? – doncherry Oct 2 '11 at 11:41
Right. I normally prefer page numbers. – lockstep Oct 2 '11 at 11:43

I agree with the suggestion of lockstep, but I would like to make it more general, as follows: use whatever numbering appears in your document.

Most often your section will be numbered "4.3" so use exactly this form when you reference it -- this way your reader won't have to think twice when trying to locate it. If, for some reason, sections are numbered without the chapter number, then use the form "section 3 in chapter 4", possibly accompanied by the page number to help the reader locate it -- in this case "section 4.3" won't remind anything to the reader.
