Sorting work which has two different volumes in translation

[Nacho]

I can't figure out how to solve this. There is a book by Raymond Hutchings called "Soviet Economic Development" (ISBN 9780631127956), which is a single volume.

The Spanish translation was done in two volumes, each one has its own ISBN (Volume I: 9788470900235; Volume II: 9788470900266). The collection as a whole has its own ISBN, despite not being available as a single volume: 9788470900228.

How should the Spanish edition be stored? Each volume as a separate edition of the original work? Do not include the individual volumes and instead create an edition with the collection ISBN? If so, which cover should be used? This poses some problems, since some people (me, for example) only own one of the two volumes.

At the moment, they have their own individual entries as books (see https://www.goodreads.com/book/show/4... and https://www.goodreads.com/book/show/4...), but should probably merged with the original work somehow (https://www.goodreads.com/book/show/1...).

Parts cannot be combined with wholes.

Thanks for your reply. So they should remain as they are, right? The three versions (the original English one and the two volumes in Spanish) as three different books.

Correct.
