We have at least one database in iLibrary that is no longer updated and therefore has come to the end of its life. This database is continued by a new database. We made the last archives of the current edition datasets, so now there are no current datasets.
When I select the DOI for the database http://dx.doi.org/10.1787/msit-data-en, I land on a page telling me "Content deleted". In fact this database is continued by http://dx.doi.org/10.1787/qits-data-en, but this is not shown on ilibrary as there has been no export since the archives were made.
If a database has archives but no current datasets, for us it is still valid and should be exported so that it can be "continued" or "replaced by" another or exist in its own right, with archives.
