Literature Review Writing Service

Comprehensive narrative, integrative, and systematic literature reviews. PhD writers locate the seminal and current peer-reviewed sources, organize them thematically, and identify the gap your study fills.

How Long a Literature Review Takes

For a dissertation, a full literature review chapter usually runs 30 to 60 pages and takes 6 to 12 weeks: 2 to 3 weeks for database searching and screening, 2 to 4 weeks for reading and building a synthesis matrix, and 2 to 5 weeks for drafting and revision. A systematic review following PRISMA takes longer because the search, screening, and quality appraisal must be documented and reproducible.

What Committees Expect From a Literature Review

Committees rarely want a list of article summaries. They look for: a documented search strategy (databases, keywords, date range, inclusion criteria); organization by themes or constructs; critical evaluation of study quality and methods; a theoretical or conceptual framework that connects to your research questions; and a clearly argued gap that justifies your study. Many reviewers check that most sources are peer reviewed and published within the last 5 years, with older seminal works where appropriate.

Formatting and Citation Requirements

In APA 7th edition, use author-date in-text citations, a hanging-indent reference list, DOIs where available, and headings that reflect your themes. Systematic reviews should include a PRISMA flow diagram and a summary table of included studies. Chicago author-date or notes-bibliography is common in history and humanities. Your university template controls margins, heading levels, and front matter.

More Than a Summary

A strong literature review does three things at once: it surveys what is known, evaluates how it is known, and identifies what is missing. Our service produces literature reviews that pass committee scrutiny because they are organized thematically rather than article-by-article, engage critically with methodology, and lead inevitably to your research question.

Types of Reviews We Write

Narrative reviews for traditional dissertation Chapter 2, integrative reviews that synthesize across paradigms, scoping reviews that map a field, and PRISMA-compliant systematic reviews with full search documentation. We can also produce supporting deliverables such as a search strategy table, a PRISMA flow diagram, and a quality appraisal table.

Frequently Asked Questions

How many sources should a dissertation literature review include?

It depends on the field and topic, but dissertation reviews commonly cite 50 to 150 sources. Coverage of the key debates and recency matter more than a raw count.

How recent should my sources be?

Many US committees expect most sources from the past 5 years, plus foundational or seminal works regardless of date. Check your program guidelines.

What is the difference between a narrative and a systematic review?

A narrative review synthesizes literature thematically to frame your study. A systematic review uses a predefined, reproducible protocol (often PRISMA) to find, screen, and appraise every eligible study on a question.

Do I need a PRISMA diagram?

Only for systematic reviews, scoping reviews, or meta-analyses. A standard dissertation Chapter 2 normally describes the search strategy in prose instead.

Can you write a PRISMA-compliant systematic review?

Yes. We follow PRISMA 2020, document the search strategy in detail, produce the flow diagram, and conduct quality appraisal using tools such as the JBI checklist or Cochrane RoB 2.

How current will the sources be?

We weight current peer-reviewed sources (typically the past 5 to 7 years) while including seminal works regardless of date.

Will the gap statement match my research question?

Yes. The literature review is built backward from your research question so the gap leads directly into Chapter 3.
