multiple entries in series, sets, coffrets etc.

Hi! I spend a lot of time on Series: Bibliothèque de la Pléiade ( fixed link )

http://lccn.loc.gov/2006464471 shows the involved book numbers:
Series: Bibliothèque de la Pléiade ; 161, 183, 548-549

Please take some time to look at the links in the comments from http://www.librarything.com/work/details/65289987 .

topics / questions:
a1) http://www.librarything.com/work/2057329/editions shows (ISBN 0785937455) This ISBN is unknown to WorldCat: http://www.worldcat.org/search?q=bn%3A0785937455 .
a2) work/2057329 should probably not be part of the seies

b) I added series information to http://www.librarything.com/work/8203202 I did not know that this is possible. I hope it makes sense.

I'm not sure I follow all the messages above, and I haven't checked all these works yet.

However, one issue you may run into is that this is a publisher's series, and thus does not meet the LT definition of a series. The only way this series can exist on LT is if it is only added to the series field for books that ONLY exist as part of this series (i.e. are exclusive to that series). That necessarily means that the series listing is going to be incomplete, because it can't be listed on works that exist in other editions published by other publishers. Some of the works in the Pléiade publisher's series are very specific to that series - very specific selections of works by an author, not found in that same selection in other edited collections - but many are not exclusive to the series.

Thus books like War and Peace (Tolstoy), Swann's Way (Proust), A Dream of Red Mansions (by Cao Xueqin), The Count of Monte Cristo (Dumas), Les Diaboliques (Jules Barbey d'Aurevilly) and even Rimbaud's Collected Works should not be included in this series, because there are other editions of those works, i.e. those works are not exclusive to the series. I'm sure there are other examples as well. I would recommend being very careful to check whether works are exclusive, and deleting series information from any that are not.

You may already know everything in posted in 4, and if so, please ignore. I think on your question 1 a, you're right that it shouldn't be part of the series, because there are multiple editions of the essays (in different languages) that are rightly combined as one work, so the book is not exclusive to the series. The questionable ISBN that you mention does seem to belong to the Pleiade version, at least when you search the ISBN on Amazon.

1b - this is ok, but I probably wouldn't list the series on this book if the series is already listed on the individual volumes in that box set.
