How to indicate doubled volume in OJS 3.1.1.4

Hi!
I need to make doubled (merged) volumes in OJS 3.1.1.4. For example, currently, we have published Volume 85/86. However, when I try to input ‘85/86’ in the field ‘Volume’, then only ‘85’ appeared. Perhaps I can manually correct some code to make possible the merged volumes?
I also tried to indicate ‘85/86’ in the field ‘Number’ and then it works fine, so it looks that OJS allows to make merged numbers but does not allows to make merged volumes. The problem is that we really need a merged volume, not a merged number.
Thanks for help!

Hello,
This has been discusses elsewhere in the Forum: Combined volume/issue numbers
There seem to be good reasons for not supporting non-numeric content in the volume field, but for us this is still a problem. We might be able to convince editors of active journals to omit double volumes. However, in the case of journals with a long history of back issues, we cannot change retroactively the fact that in certain cases (especially in difficult times) it was decided to publish double volumes. We must still find a way to display this in OJS.

Hi @novikoffav
In academic journals, a Volume means a Year. When all the issues published in a year come together, they complete a volume. Although it is strictly not recommended, for several reasons, journals might have to publish 2 issues at once in a merged form. But I have never heard about merging volumes. If your journal has reached volume 86, this means it has a history of 86 years. If you give some more tips, I can share my experiences with you.
Regards,

It seems that not enough people are aware that, in reality, there are many deviations from the rigid scheme of 1 volume = 1 year in the publication of scientific journals. This is particularly true of journals published by small to medium-sized academic societies (often also belonging to the Diamond Open Access segment), but also applies in some cases to journals from large publishing houses. Below, I will give a few examples that I am familiar with from my own field. Such examples can be found across a very broad spectrum of platforms and publishers. The phenomenon of double volumes is therefore not uncommon and should not be neglected. As long as it appears that OJS cannot deal with this phenomenon, it remains a weakness of the system.
