Two publication dates

Describe the problem you would like to solve
As mentioned at the PKP sprint this May we would like to have some changes in the way both OMP and OJS displays publication dates.

The problem is that we often publish old articles on our OJS server. See this example:Rediscovering ancient activities: Textile tools in a 3rd - 2nd century B.C. context from Herakleia (Southern Basilicata, Italy) | Archaeological Textiles Newsletter. Our oldest articles are from the early 1800’s. We do not expect to publish many books from backlists on our OMP server. But it has happened. In order to ensure that the date in “How to Cite” are shown scientifically correct we need to give the articles a publication date from the relevant year.

But we are now experiencing problems. If we do digitize and publish an old article or a book, we are expected to present the online publication date of the specific article or book in order to be registered correctly in our national bibliography. If we do that an article from 1814 will seem to be published in 2026, which will be seen as bad metadata .

Describe the solution you’d like
Is it possible to have two publication date fields in OJS and OMP? One for the original date (1814) and one for the first online publication date (2026)?

Who is asking for this feature?
We do operate an OJS and an OMP server.

Hi @thestrup,

This issue has been identified previously and should be addressed in OJS/OMP 3.5: Can't set the publication date of an issue before it is published · Issue #7165 · pkp/pkp-lib · GitHub

@rcgillis I think that the other topic is more about how to handle old articles and ensure the correct publication date. We actually need two dates. The original publication date and a date showing when something had the first original online date. So, something digitised in 2026 - but published in 1982 - would have two publication dates. First date online in 2026 and first date published in (e.g.) 1982. But it is a long post and I’ll have to read through it.
