I am writing an article for publication in a journal, and I couldn't find the answer here on Stack Exchange or in the journal guidelines. The field in question is electrical engineering.

As I'm writing my introduction, I would like to tackle different parts of the problematic in a very clear way. I'm thinking about something in the likes of (not necessarily in order):

  • Formalizing some definitions and variables that will be used;
  • Context of the problem;
  • Brief review of models used in the literature (to justify my model of choice);
  • Review of parametrization methods for models similar to mine;
  • Review of papers tackling the same problem (and therefore the "holes" that my paper will fill);
  • Objectives of the article and a brief explanation of the structure (e.g. Section II will show...).

I think that if I write all these points a single section, it will be a huge block of text (even with proper use of paragraphs and writing), and some readers may not pay attention to some important points. So I thought about breaking down my introduction in subsections, as it seems a logical solution to the problem.

I saw some articles doing this, but the majority of journal articles I have read on my area don't do this. Do you guys think it is an acceptable solution to use subsections on an introduction? Can it impact positively or negatively a review process?

    "Do you guys think it is an acceptable solution?" - Absolutely (unless journal rules specifically prohibit it). – sleepy Jun 11 at 10:01

    Why do you assume that all of this information should go into the introduction, rather than having a short and crisp introduction and some detailed sections after that? – lighthouse keeper Jun 11 at 11:11
  • @lighthousekeeper I'm following the classic <Introduction - Methodology - Results - Discussion - Conclusion> template, and I don't want to make my Methodology section less straightforward by adding discussions about the literature/state of the art. I see three possible solutions: (1) add a literature review section, even though I don't find it common on my subfield; (2) write a really long introduction; (3) break down the intro in subsections. I find the last one more logical, but I haven't really seen articles doing that. – Pseg Jun 11 at 11:15

    I'm not from EE, but from a somewhat neighboring area within CS (software engineering). We would use that classic template rather as an inspiration rather than a strict guideline, to avoid having a bloated introduction. It's fairly standard to have additional sections like "Background", "Related Work", "Overview", "Problem statement". – lighthouse keeper Jun 11 at 11:53

    Without knowing the length of the paper this is hard to answer. A sixty-page paper certainly can use subsections in the introduction. Not so with a three page paper. – Terry Loring Jun 11 at 17:41

Reserve the introduction for

  • A very brief background necessary for understanding the next three points
  • Summarizing your research question and findings
  • Explain how your contribution relates to the existing literature
  • Outline the remainder of the paper.

These are four to six paragraphs.

All of your literature review should go into a separate section, after the introduction.

    I'm not very familiar with publications in electrical engineering (the field mentioned by the OP), but as currently worded your last sentence seems to overgeneralize from some fields to others. For instance, in mathematics it's quite common to do the literature review within the introduction. – Jochen Glueck Jun 11 at 10:10
  • @Jochen Glueck Perhaps. I'm more familiar with humanities and social sciences, and here we only have a very contributions-focussed summary of the literature discussion in the introduction. – henning Jun 11 at 10:13
  • @henning Thanks for your answer :) It is indeed a good idea to do a separate section and I thought about doing that, but in my specific subdomain I also find it quite rare. Most articles privilege a long 1-2 page introduction and then a section about methodology usually follows. – Pseg Jun 11 at 10:21
  • The four paragraph introduction might make sense for a six-page paper. For a thirty page paper that would generally be very short. – Terry Loring Jun 11 at 17:23
  • @Terry Loring okay, let's say four to six then. :) – henning Jun 11 at 17:53

When writing the paper, think about how others will read it. Here is how I typically read engineering papers:

Typically I'm looking for papers on topic X. I usually have a long list (10 - 100) of papers that may or may not be relevant. I can't read them all in depth, I have to "triage" them to determine which ones to spend time on. So first I read the abstract. If that sounds interesting, then I skim the introduction and conclusion. If that sounds interesting, then I glance through the figures. If I'm still interested, THEN I start reading text in depth.

I don't know if this is how others read engineering papers, but I suspect many would (at least, I know for sure that none of my colleagues magically have more spare time on their hands than I do)

With that in mind:

  • Structured papers with well organized sections, subsections, etc: good, makes it easily skimmable
  • Long introduction: bad, I won't read it all anyway unless I've already decided that your paper is relevant based on process above.
  • Suggest that your first figure or two should serve as a "graphical abstract". Something where a quick glance at the figure will give a sense for what the paper is about, even without reading any text.

I'm going to suggest that you don't do so much in an introduction. I suspect that reviewers will say the same. Most of what you have listed should be sections of the main part of the paper, not the introduction. If the intro is so long that it gets boring, then readers may not get to the more important stuff.

I recognize that you are trying to be "logical", but that can be a mistake in an introduction. What you want to do is tell the reader why they should read the whole paper, not present most of the paper itself. But your sections seem to include nearly everything except the results and conclusions.

The key in the intro is to say what problem is being attacked, whether the methodology is standard or innovative, and what we can conclude in general from the research. Put the rest of it in sections of the paper itself.

What you seem to be wanting to do is write half or so of an extended abstract in the introduction. I'd suggest not doing that. Capture the reader's interest in a few sentences. If the various sections of the paper itself are properly named and set off, then there is little need even to write what amounts to a table of contents in the intro. Let the paper's structure do that. Point to things that are unique/innovative/interesting in the intro, but not a general outline. The good will get lost in the ordinary if you try to do too much.


Personal note: I once wrote a lesson for students that was so perfectly logical, complete, and elegant that no one understood it at all. It was beautiful, but useless for my purpose - and theirs. Logic and precision are often needed (this was Statistics) but understanding is also required or the logic is distracting and gives little insight.


However, for something sent to a journal as a first draft you can structure it pretty much as you like. Very few papers ever get published in their original form. If no one objects to your structure, then it is probably fine, though you should also consider the ultimate reader, not just the reviewers, who may have more background than the typical reader.

You certainly do not want six introductory sections --- that is excessive and it will bore your reader to tears. It should be possible to include all the things you have set out here in two sections: (1) an initial introduction without formal definitions/models that gives a non-formal introduction to the the problem and its context, the relevant literature, and what you will do; and (2) a section formalising the problem and expanding on the details of the models in the literature and how your model departs from these. If you find your explanations so long that you feel you need to break these into subsections, that is a sign that you are being insufficiently parsimoneous in your explanation. You should be able to cover all the points in your post in two sections, and it should generally be possible to cover this without so much text as to require breaking into subsections.

1. Introduction

Here is a general problem and its context

Here is some literature about the problem

Here is what my paper will do, with a brief justification

2. Defining the problem

Here are formal definitions of variables, models, etc.

Here is more detailed discussion of models in the literature that are similar to mine

Here is how my model will differ from those in the literature, and more details on the justification ...
