If you're staring at ISBN 9780357367810 on a syllabus, a used bookstore shelf tag, or a course materials page, you probably want four things fast: what the book actually is, who wrote it, what edition or year it is, and where to get it without overpaying. That last part often turns into a search for a free PDF, which is worth addressing directly before you waste time on it.
This guide does something most ISBN lookup pages skip: it shows you how to check the number itself, explains what the publisher prefix tells you about why this particular ISBN may be hard to pin down, and walks through the exact steps to confirm the title, author, and publication date before you spend money on the wrong edition.
The Book Behind ISBN 9780357367810
An ISBN lookup page that just names a title without showing its work is asking you to trust it blindly, which is exactly the gap this article fills. Before naming any bibliographic detail as fact, it needs to be checked against a live catalog record for that exact 13-digit number, not guessed from a similar-sounding title.
What can be said with confidence from the number alone is its structure: 9780357367810 is a properly formatted ISBN-13, and its prefix places it in a block assigned to Cengage Learning, a major publisher of U.S. college course materials, including many introductory health, fitness, and personal wellness textbooks.
The rest of this article shows you exactly how to turn that starting point into a confirmed title, author, and edition using free, independent catalog tools, and why doing that cross-check matters more for a Cengage ISBN than it would for most trade books.
Is ISBN 9780357367810 a Valid Number?
Yes: 9780357367810 passes the official ISBN-13 checksum test, meaning it is a correctly formed, real ISBN rather than a typo or a scam listing.
Every ISBN-13 ends in a check digit calculated from the 12 digits before it, using alternating weights of 1 and 3. For 978035736781, the weighted sum works out to 110. Since 110 is a multiple of 10, the required check digit is 0, which is exactly the final digit in 9780357367810.
That match confirms the number is internally consistent. It does not tell you the title or author by itself, but it does mean you can trust the number enough to search it, rather than wondering if a listing site or classmate mistyped a digit. The International ISBN Agency publishes the full algorithm if you want to check any other ISBN the same way.
What Does the 978-0-357 Prefix Reveal About the Publisher?
The 978-0-357 block is assigned to Cengage Learning, and that single fact explains most of the confusion people run into with this kind of ISBN.
Cengage is one of the largest publishers of U.S. college textbooks, and it frequently issues the same core content in multiple parallel formats: full print, loose-leaf, eBook, and custom campus bundles that pair the text with an access code for an online platform like MindTap. Each of those formats typically gets its own distinct ISBN, even when the underlying chapters are identical.
Introductory fitness, wellness, nutrition, and personal health courses are among the Cengage lines revised most often, sometimes every two to three years, because instructors want current guidelines and updated research citations. That means an ISBN from an earlier printing can disappear from a bookstore's active stock while it's still listed on aggregator sites, which is exactly the kind of mismatch that catches students off guard right before a semester starts.
Who Is the Author of ISBN 9780357367810?
The publisher prefix cannot tell you the author on its own; only a direct lookup of this specific 13-digit number can, so the reliable method is to check at least two independent sources and confirm they agree.
Start by pasting 9780357367810 into the search box at Open Library, then repeat the same search on WorldCat, which pulls records from thousands of library catalogs worldwide. If both return the same author name, title, and format, you can treat that as a confirmed match.
If only one source returns a result, or the two disagree on author or subtitle, don't guess. Custom and bundled editions occasionally get mislabeled in aggregator databases, so a third check, either Google Books or a direct search on your campus bookstore's site using the ISBN field, is worth the extra two minutes before you buy.
What Is the Publication Date of ISBN 9780357367810?
The publication date tied to this ISBN is whatever year the direct catalog lookup for this exact number reports, not the year of an earlier or later edition that happens to share a similar title.
This distinction matters more with Cengage titles than with most publishers because the company often keeps a title and subtitle unchanged across editions while quietly assigning a new ISBN to each revision. Searching by title alone can pull up the wrong year's edition, which is a common way students end up with a mismatched access code for online homework platforms in a fitness or wellness course.
To avoid that, check the copyright page shown in a retailer's "look inside" preview, or match the edition number and year listed on your syllabus word for word against what WorldCat or Open Library return for this specific ISBN before you order.
