For an article, compare the complete record
When a DOI is printed with an article, follow it and compare the title, author list and publication details. If you have a preprint, check whether a separate published version exists and which one you are quoting.
Do not change a preprint reference into the journal version while keeping page numbers or wording taken from the earlier file. The version matters when someone tries to reproduce your reading.
For a book, check the physical or electronic product
Use the ISBN and edition statement from the version in front of you. A paperback, hardback and ebook can have distinct identifiers. A title alone may lead to a different publication year or a revised edition.
For a chapter written by separate authors, record the chapter and the containing book as the required style specifies. The book's ISBN helps locate the container; it does not replace the chapter title, author or page range.
Keep a short comparison record
Save five fields while checking: source type, identifier, title, version or edition, and the location of the passage you used. If a lookup disagrees, inspect the disagreement before editing the reference.
Citelle accepts DOI, ISBN, links and titles, and lets you edit fields manually. A lookup is a starting record rather than a command to overwrite the publication's evidence. On this website, the ISBN checker only validates arithmetic and the manual citation builder only formats your entries.
- Compare records with the item itself.
- Keep page or section notes separate from the identifier.
- Mark uncertainty rather than supplying guessed metadata.
