A book was originally published in two volumes and got a translation in three volumes. They are not combined but can the three volumes get the original publishing date from the two volumes? If not, should they get the date from the three volumes or left blank as they are now?
It's worth to mention that the two original volumes were published a month apart the same year so if the exact date could not be applied maybe the year can.
