However, you might find a DOI in these situations:
* For individual chapters in an edited book: If the book is a collection of chapters by different authors, each chapter *might* have its own DOI. Look for the DOI at the beginning or end of the chapter itself, or in the chapter's bibliographic information.
* For online books published through platforms with DOI assignment: Some publishers assign DOIs to books published exclusively online, particularly through platforms designed for electronic books. Check the book's online webpage or metadata.
* For specific versions of a book: A publisher might assign a DOI to a particular ebook version or a specific edition of a book, distinct from other editions.
If you can't find a DOI for the book itself:
You should use other identifiers for proper citation, such as:
* ISBN (International Standard Book Number): This is the standard identifier for books and is almost always present. Use this in your citations.
* ISSN (International Standard Serial Number): This is for periodicals like journals and magazines, so it's not relevant to books.
Where to look for a potential DOI:
* The book itself: Look on the title page, copyright page, or the back cover.
* The publisher's website: Search for the book on the publisher's website. The book's page might list a DOI.
* Online library catalogs (e.g., WorldCat, Google Scholar): Search for the book; the catalog record might include a DOI if one exists.
* Within a citation of the book: If you found the book cited in another publication, the citation might include the DOI.
In short, while it's less common, a DOI *might* exist for a book, but it's not guaranteed. The ISBN is the reliable identifier to use in the absence of a DOI.
