The history tables are set that way so that people can tell which catalog it was in. It is easier for us to update a catalog than to state a particular date and we find that it is clearer to the reader, as it states the catalogs it can be found in. For example, if an item has April 2018 to May 2018, then it was in the April and May catalogs.
