Reference Duplicate Finder
Paste a bibliography, one reference per line, to find confirmed and probable duplicate entries. This checks only the text you provide — it never queries Crossref, PubMed, or OpenAlex, and nothing you paste leaves this browser.
Drag and drop a file here, or click to browse.
