I'm writing to ask if anyone has dealt with this before. I have this title, The Guernsey Law Reports. They began publishing the reports in print in 2019, starting with a volume of reports from the years 2000-2002. Now they are issuing retrospective volumes, with reports prior to 2000. I have no idea how far back in time the publisher is going to go.

My question is this: what do I do about recording start dates for the time periods covered by the Reports, since they will be covering reports issued in the future, as well as the past? I suppose that, technically, they began with 2000, because that was the first volume published. But now that they are publishing retrospective volumes, we don't know when they actually "began". Would you just cover this with a note field? Or do something else?

Thanks for your time and consideration.
