Different edition of a book

[Subhash Khode]

I would like to know that whether different editions of same title should be treat as different titles or not. For

example if we have 3rd , 4th and 5th edition of Data communication by forouzan then can we count it

3 titles or not?.

[Pawan Kumar]

Yes, it is 3 titles.

They will be treated as same title

[Veeresh Hiremath]

They are treated as same titles.  But, I am at times amused why it is so? When we say it is same title then - author should be same, title should be same and more importantly the thought content of the material should be same.  when there is a different edition of the book, obviously there shall be addition or deletion of thought over the previous edition (different thought content).  Therefore the book (material) should be treated as a different title.  This is what I honestly feel

[priyanka vasudeva]

and what about if the next edition has a slight change in title then also we  take it as same title ??

Actually we can also take it as different title ? actually it s up to you how to treat various matters in library because there is no where written about such treatments of books.

[Sarvesh]

The matter cannot be left to the whims and fancies of the librarian.  There should be uniformity and standardization of procedures.
Considering a material as a new title purely on the basis of the difference in ISBN alone is incorrect. 
Supposing I have a book in print format.  It has got some ISBN.  Tomorrow if the same is publised in an e-book format, then  it will be assigned different ISBN Number though the thought content remains the same. ISBN also changes when the copy rights of the same title are transferred to some other publiser and the same book emerges as a product of different publiser.  Therefore the only logical reasoning to be applied while considering a book as a different title is the difference in thought content.
I therefore agree that different editions of the same title have to be treated as different titles.

[Subhash Khode]

As we know ISBN number is unique for a book but if ISBN number change in different edition of same books published by same publisher then is should be treat as different title

[priyanka vasudeva]

that is what i am trying to say the logical reasoning behind the matter and that depends on the intellect of librarian. There is no written conduct that could guide librarians so that standardization could be maintained .
