What does the ISBN number mean in books ? .. so each and every book has a different number?

or judt different titles?|||International Standard Book Number.


And yes, so every book has its own number.|||It is simply an ID number; yes, each book has its own unique number. Somewhere in the first few numbers, of the ten numbers in the ISBN, are the numbers that identify the publishing house of the book, BTW.|||ISBN stands for the"International Standard Book Number", which is a 10-digit number that uniquely identifies a book and/or book-like products published internationally.





The purpose of the ISBN is while enabling a person to identify one title or edition of a title from one specific publisher, which is unique to that edition, also allowing for more efficient marketing of products by booksellers, libraries, universities, wholesalers and distributors.





The 10-digit (in some cases includes alphanumeric as well) ISBN number is formatted in 4-parts, each part having the following meanning:





1. Group or country identifier which identifies a national or geographic grouping of publishers;





2. Publisher identifier which identifies a particular publisher within a group;





3. Title identifier which identifies a particular title or edition of a title; and





4. Check digit is the single digit at the end of the ISBN which validates the ISBN.





Is this question a homework assignment?|||Faith is correct, but ISBNs are now converting to 13-digits.





But, yes, each book title (and sometimes edition) will have it's own ISBN. In fact, if you know the ISBN of a book, you can go into a book store with that number alone and find the book you're looking for.
