How can I find a DOI for book?

Finding a DOI (Digital Object Identifier) for a book can be tricky because not all books have them. DOIs are more commonly assigned to journal articles and chapters within edited books. However, some books, especially those published electronically or by publishers who embrace DOIs, will have them.

Here's how to try and find a DOI for a book:

1. Check the book itself: The easiest place to look is the book itself. The DOI is usually found on the copyright page, the title page, or the back cover. It will look something like this: 10.XXXX/YYYYYYYYY.

2. Search the publisher's website: Go to the publisher's website and search for the book's title or author. The book's page on their site may list the DOI.

3. Search Google Scholar or a similar database: Search for the book title and author on Google Scholar or another academic search engine (like Scopus, Web of Science). If the book has a DOI, it should be listed in the search results.

4. Use a DOI lookup tool: Several websites allow you to search for DOIs using the book's title, author, or ISBN. However, these are not guaranteed to find DOIs for books if they haven't been assigned.

5. Check WorldCat: WorldCat is a global catalog of library collections. While it might not directly show a DOI, the record for the book might contain links to online versions that do include a DOI.

6. Check the library catalog: If you found the book in a library, check the library's online catalog entry for the book. It might list a DOI.

Important Note: If you can't find a DOI for a book, it doesn't mean the book is invalid or not credible. DOIs are a relatively recent development, and many older books or books from smaller publishers won't have them. You can still cite the book using the standard bibliographic information (author, title, publisher, year, etc.).
