Reference integrity checking for authors, lecturers and research supervisors
This browser-based reference checker is designed for journal authors, students, university lecturers, professors, thesis supervisors and editorial teams who need a fast technical audit of a manuscript bibliography before submission, review or final grading.
The IJPSC Reference Integrity Checker is a browser-based academic bibliography audit for journal authors, university lecturers, professors, thesis supervisors and editorial teams. It examines whether references can be technically identified, whether DOI metadata from Crossref, DataCite or OpenAlex corresponds to the cited title and authors, whether sources are duplicated, and whether author-year citations in the manuscript are represented in the bibliography.
What does a reference integrity report detect?
The report identifies unresolved DOI, DOI-to-title mismatches, possible author or year inconsistencies, duplicate bibliography entries, duplicate DOI values, missing publication years, unusually incomplete references, uncited bibliography entries and in-text citation keys without a corresponding reference.
What does the tool check step by step?
The local analysis reads the PDF text in the browser, identifies the likely reference section, extracts single bibliography entries, searches for DOI patterns, compares detected references with in-text author-year citations and, if enabled, validates DOI and bibliographic metadata through Crossref, DataCite and OpenAlex. The final report groups results into verified, manual-review and critical signals. Exact DOI resolution is treated as the primary bibliographic identity anchor, while title, author, year and source comparisons remain transparent supporting evidence.
Who should use the Reference Integrity Checker?
The tool is suitable for manuscript preparation, thesis supervision, seminar teaching, editorial pre-checks and research methods training. It is especially useful when a supervisor wants to identify uncited bibliography entries, duplicate references, unresolved DOI strings, suspicious metadata mismatches or likely gaps between citations in the text and entries in the bibliography.
Is this a plagiarism checker?
No. It is a reference provenance and citation-alignment audit. It can expose warning signs associated with copied, fabricated, incorrectly attributed or padded reference lists, but it does not compare the full manuscript against a global corpus and cannot prove plagiarism or academic misconduct.
Does IJPSC receive the uploaded PDF?
No. PDF text extraction and the initial structural analysis take place locally in the visitor's browser. Only individual reference strings or DOI identifiers are transmitted for metadata verification. The PDF itself remains on the visitor’s device. The manuscript file itself is not uploaded to the IJPSC server.
Can the result be saved as a PDF?
Yes. The report data are sent to the IJPSC server only after analysis, converted into an A4 landscape PDF and returned as a direct download. The manuscript PDF itself is never uploaded. CSV, JSON and standalone HTML exports are also available.
