A 70,000-word thesis does not become one 5,000-word paper. It usually becomes two or three, and deciding which is the first job.
Decide how many papers are in there
Each paper needs one question, one dataset or analysis, and one conclusion. Map your chapters against that test. A thesis with three empirical chapters often yields three papers; one with a single study yields one, plus perhaps a methods paper.
Publish the strongest first. It establishes the work and gives the later papers something to cite.
What has to be cut
- The literature review. Forty pages becomes six paragraphs. Keep only what is required to establish the gap this paper fills.
- Methodological justification. Examiners want to see you understood the alternatives. Reviewers want to know what you did.
- Every result. A paper reports the findings that answer its question, not everything you calculated.
- The reflective passages. What you learned as a researcher belongs in the thesis, not the paper.
If a section exists to demonstrate that you know something, cut it. If it exists to support the argument, keep it.
What has to be rewritten
Voice. Theses hedge extensively, because examiners probe overstatement. Papers state findings directly. Remove the accumulated qualifiers.
Structure. Thesis chapters build cumulatively. A paper is self-contained: IMRaD, with an introduction that assumes no knowledge of your other chapters.
References. A thesis may cite 300 sources; a paper cites 40 to 60. Keep the ones doing work.
Prior publication and your repository
Most journals do not consider a thesis in an institutional repository to be prior publication, but policies differ and you should check the specific journal. Where in doubt, declare it in the cover letter — disclosure protects you, silence does not.
Authorship
Settle this before writing, not after. Supervisors who contributed to design, analysis or interpretation are normally authors; those who only provided funding or facilities normally are not. Use ICMJE criteria and have the conversation early.
A practical sequence
- Map chapters to potential papers, and rank them.
- Choose the target journal first — its scope shapes what you emphasise.
- Write a fresh 250-word abstract for the paper, not the thesis.
- Rebuild the introduction from scratch. Do not edit the thesis version.
- Compress methods to what is needed for replication.
- Select results, rebuild tables and figures to journal specification.
- Write a discussion that answers this paper's question only.
