How to Write an Introduction to a Literature Review

How to Write an Introduction to a Literature Review

You've read through dozens of papers. Your notes are a mess of highlighted PDFs and half-finished bullet points. And now you're sitting there wondering how to turn all of that reading into a single opening section that actually makes sense.

The literature review introduction trips people up more than almost any other part of a dissertation or research project. It's not because the writing itself is hard. It's because you're trying to summarise a whole field of research into a few paragraphs, while also explaining why your own work fits into it. That's a lot to juggle in a short space.

In this guide on how to write an introduction to a literature review, we will walk you through exactly what needs to go into that opening section. We will also guide you on how to structure it properly and what are the criteria need close attention. Let's get into it.

What Is a Literature Review Introduction?

A literature review introduction is the opening section that tells the reader what the review will cover, why the topic matters, and how the review is organised. It sets expectations before the reader gets into the detailed discussion of sources, so they know what to look out for as they read on.

Unlike the main body of a literature review, which works through existing research in detail, the introduction stays at a higher level. Think of it as an orientation point. It doesn't need to summarise every study you're about to discuss. It just needs to point the reader in the right direction and explain why the journey is worth taking.

Once that expectation is set, the rest of the review has something to build on.

Why the Introduction Matters More Than Students Think

It's easy to treat the introduction as a formality, something to get through before reaching the "real" analysis. But markers often use this section to judge how well a student understands their own research area, before they get to the detailed discussion of sources.

A vague or rushed introduction makes even strong research sound unfocused. A clear one signals, from the very first paragraph, that you know exactly what you're reviewing and why. That first impression tends to shape how generously the rest of the work gets read. This isn't unique to literature reviews either; the same logic applies to assignment introductions as well. With that in mind, it's worth knowing exactly what needs to go into it.

The Things Your Introduction Needs to Cover

Once you know your core idea, there are a few things worth including in the opening section. Think of them less as a checklist and more as pieces that fit together to make the paragraph work.

• A bit of background on the topic. One or two sentences to place the subject in context. Why does this area matter? Why are people studying it right now? It helps the reader to analyse why this review matters.
• A reason your review exists. This is the part people often miss. It's not enough to say what you're reviewing; you need to answer only why. It can be because of a gap in existing understanding, an ongoing debate, or a shift in how people now think about the topic. Any of these can work.
• What your review actually covers. Readers need clear boundaries. What time period are you looking at? What kinds of sources? What's your angle? Setting this out early means nobody can later say you "missed" something that was never part of your plan.
• A quick preview of what's ahead. One sentence near the end is enough to tell the reader how the review is organised, whether that's by theme, by time period, or by method. Just let them know what to expect.

You don't need a separate paragraph for each of these. Most of the time, they can all fit into four or five simple sentences. The goal isn't to write more; it's to make sure nothing important gets left out.

A Simple Way to Think About the Structure

If you're not sure how to arrange these four elements, so picture this as a funnel. Start broad, with the general topic and its context. Narrow down to the specific purpose of your review. Narrow again to the scope. Finish at the most specific point: the structure of what's coming next.

This shape mirrors how most academic readers expect information to be delivered, moving from the general to the specific. It also naturally avoids one of the most common mistakes, jumping straight into detailed source discussion before the reader has any context for why it matters.

Example of a Literature Review Introduction

Here's a short example that pulls all four elements together, followed by a breakdown of what each part is doing.

Example: Remote working has become a significant feature of modern employment, particularly following the widespread shift in working practices during the past decade. While much has been written on its effects on productivity, less attention has been paid to its impact on employee wellbeing over the long term. This review examines the relationship between remote working arrangements and employee wellbeing, drawing on peer-reviewed studies published between 2015 and 2025. The review is organised thematically, beginning with physical health outcomes, followed by mental health considerations, and concluding with organisational factors that influence these outcomes.

Here is a clear breakdown of what each part is actually doing:

• Topic and context: The first two sentences show that remote working is a topical issue. There is also mentioned a specific gap, wellbeing over productivity, which will be discussed in this review.
• Purpose: The third sentence shows the purpose of this review. It discusses how remote working will impact wellbeing.
• Scope: In addition to the third sentence, this sentence specifies the source type and time frame and lets readers understand what will not be included in this review.
• Structure: The fourth sentence mentions three themes which the review will cover.

Where Students Go Wrong (And How to Fix It)

Now that you've seen how the four elements work together, it's worth looking at where things usually fall apart. Most mistakes trace back to one of the four parts which are mentioned below with their proper fixes:

• With the topic and context: Students often either skip this entirely and jump straight into their purpose or end up summarising half the field before getting to the point.
• The fix is simple: one or two sentences of context, just enough for someone unfamiliar with the area to follow along, then move on.
• With the purpose: A common slip here is being too vague. Phrases like "this review looks at various aspects of remote working" don't actually tell the reader anything.

Compare that to "this review examines the relationship between remote working and employee wellbeing," which says exactly what the review is doing. The fix is to be specific and direct, even if it feels slightly blunt at first.

• With the scope: Leaving out scope entirely is probably the most common mistake of all. Students assume the reader will just figure out the boundaries as they go, but that puts unnecessary pressure on the reader to guess.

State the time frame, source type, or focus area clearly. It takes one sentence and saves a lot of confusion later.

• With the structure: This is the part most often left out completely. Without a closing sentence the review can feel disorganised even when the research inside it is genuinely strong.

A single line at the end, "this review is organised thematically, covering X, then Y, then Z," is all it takes to fix this.

What's worth noticing is that none of these mistakes come from weak research. Stepping back and reading your introduction as though you know nothing about the topic is usually the quickest way to catch these issues yourself. And since a literature review is often just one chapter within a much bigger piece of work, it's worth applying this same thinking to your dissertation introduction for writing it effectively.

Final Thoughts

Writing the introduction to a literature review isn't really about finding the perfect words. It's about making sure four simple things are covered: what the topic is, why your review exists, what it does and doesn't include, and how it's organised. Get those four in place, in that order, and the rest tends to follow naturally.
