Let's assume there is some John Doe, who is an author of Some Book.
This book was published by Some Publisher in 1800, in 2 volumes. Then, it was published again in 1805, by the same publisher, with minor corrections.
And in 1810 it was published again, by the same publisher, but in 3 volumes, with images, preface, glossary, on handmade paper and in very limited quantity (only 300). And much more pricey, of course.
And this pricey "version" was published again, in 1815, by the same publisher, with minor corrections.
Do we have 1st, 2nd, 3rd and 4th editions here?
Or do we have 1st and 2nd and again 1st and 2nd editions?
I have already read the Wikipedia article about "edition", and it seems this question could be answered differently, i.e. from the bibliographical point of view, and from the publisher's point of view, and the publisher's point of view isn't consistent.
But I'm not sure.
Please give me some light on it. Probably there exists some strong and rigid classification for it?
