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 a 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.

How Did The ISBN Code Come About? 

A retired Irish statistics professor came up with the 9-digit Standard Book Number in 1966 for several British bookstores in an effort to keep track of their internal inventory. This stock number helped booksellers, warehouses, publishers and others identify books quickly, especially with the introduction and popularity of computers.

In 1970, the International Organization for Standardization permitted the use of a 10-digit code known as the International Standard Book Number (ISBN). This number increased to 13 digits in 2007 for an array of reasons. The ISBN isn’t the only code used. There are also the International Standard Serial Numbers (ISSN), International Standard Music Numbers (ISMN) and the International Standard Recording Codes (ISRC). Read more about ISBN history here.

What’s The Purpose Of The ISBN?

The ISBN is used to identify books – with books before December 2006 using a 10-digit number and anything afterward identified by 13 digits. An ISBN will read a bit like this: 975-1-543211-04-4

  • The first three numbers are the ISBN
  • The second number designates the country or language
  • The third set of numbers denotes the publisher
  • The fourth set of numbers is the title or format
  • The last number is the check digit verifying the other digits’ accuracy

When somebody is looking up the book, the ISBN owner is noted as the publisher of record. Don’t mistake the ISBN for copyright, as it’s not the same. As ISBN doesn’t mean you have immediate copyright. You can find the ISBN on the back cover of a book and listed on the front side with the publisher and other pertinent information. It’s also a part of the metadata.

What Exactly Is A Metadata?

Metadata denotes information about the book, such as title, subtitle, book description, etc. Other information may also be included, such as a summary, bio and table of contents.

10-digit ISBN vs. 13-Digit ISBN

The 10-digit ISBN is different from the 13-digit ISBN, and price doesn’t factor into it. If you know what the ISBN represents, you can know which ISBN is being used. Many people feel the number 10 is the same as the 13-digit ISBN, but it’s not. But, one thing to note is that any 10-digit ISBN will also have a corresponding 13-digit number. The US ISBN Agency came up with a 979 prefix for the dwindling 978 inventory in 2020, with a note that no 979 prefix has a 10-digit ISBN.

You can learn all about books through their ISBN, and, from the other side, if you don’t know what the ISBN of a book is, you can look it up through ISBN websites by title or by author.

An ISBN lookup is a critical component of selling books. Students can use this number to sell or find books via any website such as BookScouter. With an ISBN lookup price comparison site like BookScouter, you can quickly sell your books to a buyback vendor who wants them and pays the most.

ISBN Differentiates Between Editions 

The ISBN differentiates between a book’s many editions. It’s not uncommon for textbook publishers to release a new edition of the same book every so often. While you can buy a used book for a class, you might want to make sure that the professor has assigned that very edition.

For online purchases, the ISBN is a necessary component to buying the right one. Of course, you need to know where to find the ISBN. If you have no idea what you’re looking for, you can’t look for it. The ISBN is present on any book. You can use the information and paste it into a search engine.
