Adding new book - multiple books with the same ISBN

[Jovan]

Hello. I've tried to add a book "Vođi Francuske revolucije" by Slobodan Jovanović. The ISBN number is 86-13-00435-0. However, this book is the first book of the series "Sabrana dela Slobodana Jovanovića" (The collected works of Slobodan Jovanović) in which all the books have the same ISBN. The book "Iz istorije i književnosti" (http://www.goodreads.com/book/show/10...), which is the 11th book of the series, is already added, so I can't add other books from the series (unless I omit ISBN numbers).

Any help or suggestion, please?

Was the series sold (originally, by the publisher and direct distributors) as a set, or as individual volumes?

I don't know. This edition is from 1990, I can only assume that it was sold individually since I own only 10 of the 12 books, and they were bought shortly after the publishing.

Then it's ok to add the other volumes, but yes, you will have to omit ISBNs.

Will do, thanks. :)
