About UBN:

What is UBN?

UBN is Universal Book Number.

UBN is a unique identification number for a book. Universal Book Number is recognized globally and catalyzes the sale of book to bookstores and librariesUBN allows scientifically management of books and their discoverability at global level. Universal Book Number eliminates the ambiguity in identification of books. While numerous book titles, published by different publishers may have same titles across the world, it creates huge confusion among readers. UBN serves here as a great tool to correctly identify a book. Since all such books will carry different UBN. UBN is assigned to international as well as local editions of books. If edition of a book is changed, (e.g. next edition) it would require new UBN. If content is same, it needs to assign different UBN for print and/ electronic version, at free of cost. UBN is affected by format of file (e.g. jpeg, MS-Word, PDF, etc). A book in different languages needs to be assigned separate UBN, at free of cost. N (any) number of copies may be produced for a book, assigned with single UBN.
