RIS Library Overlap Auditor

How to use RIS Library Overlap Auditor

Review possible overlap before combining reference exports from separate libraries. Choose bare DOI equality or an exact title/year key; the report groups matching records without deleting or merging anything. Different input files, unkeyed records and original tag evidence stay visible for a human decision.

1. Choose one or more small RIS library exports, or load the two generated fictional examples.
2. Choose the exact key policy and inspect candidate groups, cross-file provenance and every unkeyed reason.
3. Download the review evidence, compare original records and make any merge decisions separately in your reference manager.

Good to know

• Choose 1–8 well-formed UTF-8 RIS files, at most 200,000 bytes each and 400,000 bytes together. Each file has at most 4,000 lines and 300 records; all files together have at most 500 records. One initial BOM per file is recorded and removed.
• Strict two-character uppercase/digit tags, two spaces, hyphen and an optional space/value. Every record begins with TY and ends with empty ER. Only explicitly indented, nonblank continuation lines are accepted. Unknown/repeated fields are retained; nested TY, malformed tags and unterminated records are refused.
• DOI mode requires exactly one bare DOI-shaped DO value and folds only ASCII A–Z; it does not strip URLs or check DOI registration. Title/year mode requires exactly one TI or T1 and exactly one PY or Y1 beginning with a four-digit year. Title case, punctuation and whitespace remain exact; conflicting/repeated key fields leave a record unkeyed.
• Equality produces candidate groups, not proof of duplicate publications. No fuzzy title matching, author reconciliation, automatic merge/removal, citation formatting or reference-manager database edit occurs. Original source and unknown field content can contain private notes or attachment paths; no attachment or URL is opened. JSON output has the shared 1,000,000-character cap.
• Processing is local. Output is limited to 1,000,000 text characters unless a stricter file limit is stated.
