Some students are under the mistaken impression that the ISBN is used only to classify textbooks. However, this number is used in selling all kinds of books. People looking to get a price quote on a book or get more information about it can visit an ISBN database or any other book search website and look up a book by the ISBN – this interaction is known as ISBN search or ISBN lookup. ISBN search sites provide details of a book, including title, author, publisher, etc. If a person is interested in purchasing a book, the ISBN helps to find it.
If you want to sell your old textbooks and outdated books but don’t know their ISBNs, this short guide is for you. We’ll help you find ISBNs on a book, and if there are none, we’ll give you a few tips on how to sell books without ISBNs, too.

If you need to pull up book data for millions of books (e.g., from the standard information book title, author, and cover art to less conventional data such as book reviews and price info), where can you get it? By accessing a book database, obviously. In this article, we’ll review and analyze the most popular book databases (both paid and free) with relatively open APIs that can help you retrieve book information by ISBN.

There’s plenty of information about listing and selling regular ISBN-13 books. However, what about the books that don’t have an ISBN? How do you deal with them? For one thing, such old books may not have any value; for another, some out-of-print books can be rare collectibles you can sell quite profitably. Therefore, knowing how to find and evaluate as well as where to sell books from the pre-ISBN era is an advantage you can use as a bookseller.

In the publishing industry, each book is given a unique identifier called the ISBN (International Standard Book Number). This code acts as a digital fingerprint, simplifying cataloging, distribution, and sales tracking. The ISBN system assigns meaning to the numbers, providing a range of information about the book.
As the publishing industry progresses, so does the ISBN system. It has transitioned from a 10-digit to a 13-digit format and now includes a 979 prefix to accommodate the diverse range of published materials. This blog post will explore what an ISBN is, how it came about, and its role in simplifying the complex world of books and publications.

The U.S. ISBN Agency has been assigning the 978 prefix to 13-digit ISBNs since 2007. In the previous articles, we’ve discovered what an ISBN is and explained the difference between 10- and 13-digit ISBNs and how both systems could be contained with the help of the 978 prefix. However, blocks of ISBN-13s built on existing ISBN-10s are exhausted. Therefore, the U.S. ISBN Agency has begun assigning ISBNs starting with the prefix element 979.
The creator of the ISBN on your book has an unbelievable life story. Learn more about the man behind the numbers, Emery Koltay.

What is it for, and where did it come from?
W. H. Smith, who was the largest single book retailer in Great Britain, became computerized and wanted a standard numbering system for all the books it carried. They constructed the Standard Book Numbering system (SBN), which was introduced in 1967. In 1970 the ISO, International Organization for Standardization, which consisted of several countries, adopted this standard system. It evolved into the ISBN numbering system and is now the standard in approximately 150 countries.
