How to avoid self-plagiarism in PhD Thesis || Own Published Papers in PhD Thesis || Hindi || 2023

Self-plagiarism in a PhD thesis isn’t about “stealing” someone else’s work—it’s about whether previously published material is reused in a way that misrepresents it as new. The core fix offered here is procedural: define what counts as self-plagiarism under UGC-style expectations, then either (1) exclude the overlapping sources from similarity checks and clearly justify what’s reused, or (2) obtain explicit permission from the original publisher and document that permission in the thesis submission package.

The transcript frames the main anxiety as a similarity-report problem. A typical workflow described involves running a plagiarism/similarity check (the example given mentions a figure like 16% initially, then repeated checks that still don’t drop below a threshold). The key point is that similarity percentages alone can be misleading—what matters is whether the overlap comes from the author’s own earlier papers and whether the thesis submission system and university policy allow that reuse. If the institution permits removing certain sources from the similarity calculation, the author should exclude the self-published paper entries and provide the required supporting documentation.

A major emphasis falls on legitimacy and transparency. “Self-plagiarism” is treated as a compliance issue: if the earlier paper is reused without proper citation, acknowledgment, or permission, it can be viewed as claiming the reused text/data as entirely new. The transcript stresses that proper credit includes identifying where the earlier work appeared (journal/conference details), giving full references, and—when required—providing publisher permissions. It also notes that many publishers allow reuse of an author’s own work in a thesis context, but the thesis must still include the correct citation trail and, in some cases, a permission letter.

The transcript then outlines how to obtain permission. The suggested approach is to contact the publisher with a formal request stating that the work has already been published and will be reused in a PhD thesis. The request should include specific bibliographic details (paper title, where it was published, volume/issue, and the author’s thesis context). A template-style email is described, along with the idea of copying relevant parties (such as the publisher’s email and the author’s supervisor/department contacts). The transcript also advises checking publisher websites for reuse policies; if the publisher explicitly allows thesis reuse, the author can proceed with citations and any required documentation.

Finally, the transcript connects policy to practical submission steps. It describes using similarity-check exclusion fields in institutional forms (including listing the overlapping sources and providing reasons for exclusion), and attaching the necessary reports and supporting documents—such as the similarity report and any “permission/verification” artifacts the university expects. The warning is that repeated rewriting and careless handling of excluded sources can create new ethical and administrative problems later, including potential issues around data integrity and misalignment between the thesis text and the similarity/exclusion records.

Overall, the message is that self-reuse is manageable when handled with clear attribution, correct documentation, and—where needed—publisher permission. The fear of “getting caught” is replaced by a compliance workflow: understand the definition, verify institutional rules, exclude or cite properly, and keep the paperwork consistent with what appears in the thesis and similarity reports.
