Literature Review Writing Service

A literature review that summarises one paper per paragraph reads as an annotated list and marks like one. Assignment Byte writes reviews organised by theme and argument, where sources are set against each other rather than queued up in turn.

We search properly, appraise critically, and finish by naming the gap your own study is positioned to fill.

What we help with

Search Strategy — Databases, keywords, Boolean strings and documented inclusion criteria.
Thematic Synthesis — Structure by theme and debate, not one paragraph per paper.
Critical Appraisal — Methodology, sample, limitations and strength of evidence assessed.
Gap Identification — A clear statement of what remains unanswered and why it matters.
Review Types — Narrative, systematic, scoping and PRISMA-guided reviews.
Referencing — Harvard, APA, Vancouver or IEEE with an accurate reference list.

Two reports, issued with every delivery

Every assignment ships with a similarity report and an AI-writing indicator read, so you can see exactly what a marker would see before you submit — not after.

A similarity report, not a bare number — You get the full Turnitin-style similarity report, not just a percentage. Quotes, references and common phrases inflate a raw score without meaning anything — the report shows which matches actually matter.
An AI-writing indicator read — Alongside the similarity check, every draft is passed through an AI-detection read so you know how it is likely to score before your university's own checker does — with no surprises at submission time.
Every flagged passage explained — If a passage is flagged on either report, we tell you why and what it would take to bring it down — rather than handing you a score and leaving you to guess.
Run on your own brief — The checks run against the work written for you specifically — never against a shared or resold document — so the reports reflect your submission and nothing else.
Delivered with time to act on it — Reports come with the draft, not after your deadline, so there is time to ask for a revision if anything needs a second look before you submit.
No promised percentage — We will not promise a specific similarity or AI score in advance — anyone who does is telling you what you want to hear, not what the report will say. What we promise is that you see the real numbers before you submit.

Assignment Byte is an independent academic support service, not Turnitin, iThenticate or any university's own integrity office, and we do not control how a receiving institution reads either report. Read more on how similarity checks work, what an AI-writing indicator actually measures, and your institution's academic integrity policy before you submit anything.

Synthesis rather than summary

The defining failure of a weak literature review is structure by source: a paragraph per study, each summarising method and findings, in no particular order. A strong review is structured by theme or by debate, with each paragraph drawing on several studies to make a point about the field.

Synthesis means saying where authors agree, where they conflict, and why that conflict might exist — different populations, methods, time periods or definitions. That explanation is the analytical contribution being assessed.

The review should end by establishing the gap your work addresses, and the gap must follow visibly from what came before rather than appearing as an assertion in the final paragraph.

Search strategy and transparency

Systematic and semi-systematic reviews require the search documented: databases searched, search strings with Boolean operators, date range, inclusion and exclusion criteria, and the number of records at each stage. A PRISMA flow diagram is often expected and is straightforward marks.

Even for a narrative review, saying how sources were found signals rigour. Reviews built on whatever the first page of results returned are visible to an experienced marker.

Inclusion criteria should be defensible and applied consistently. Excluding non-English sources is acceptable if declared as a limitation; excluding studies that disagree with your argument is not.

Critical appraisal and currency

Appraisal means evaluating quality, not reporting findings. Sample size and selection, design appropriateness, measurement validity, conflicts of interest and analytical choices all bear on how much weight a study should carry.

Use a recognised appraisal tool where the discipline has one — CASP checklists in health research, for instance — and say which you applied.

Currency requirements vary by field and are usually stated in the brief. Where a seminal older work is essential, cite it and explain why. We write to your required style with sources you can retrieve and verify.

Frequently asked questions

How recent are the sources?

We prioritise peer-reviewed work from the last five to ten years unless your topic calls for seminal older texts, and we can work to a date range you specify.

Can you follow PRISMA?

Yes — including the flow diagram, documented inclusion and exclusion criteria and a screening record.

Can you use a reading list I have already collected?

Absolutely. Send your sources and we build the review around them, adding others only where there is a gap to fill.

Will I get the full-text sources?

We provide complete references for everything cited and can supply DOIs so you can retrieve each paper through your library.
